STM32 Nucleo-64 boards (MB1136)
Introduction
The STM32 Nucleo-64 boards based on the MB1136 reference board (NUCLEO-F030R8,
NUCLEO-F070RB, NUCLEO-F072RB, NUCLEO-F091RC, NUCLEO-F103RB,
NUCLEO-F302R8, NUCLEO-F303RE, NUCLEO-F334R8, NUCLEO-F401RE,
NUCLEO-F410RB, NUCLEO-F411RE, NUCLEO-F446RE, NUCLEO-L010RB,
NUCLEO-L053R8, NUCLEO-L073RZ, NUCLEO-L152RE, NUCLEO-L452RE,
NUCLEO-L476RG) provide an affordable and flexible way for users to try out new concepts
and build prototypes with the STM32 microcontrollers in the LQFP64 package, choosing
from the various combinations of performance, power consumption, and features. The
ARDUINO® Uno V3 connectivity support and the ST morpho headers provide an easy
means of expanding the functionality of the Nucleo open development platform with a wide
choice of specialized shields. The STM32 Nucleo boards do not require any separate probe
as they integrate the ST-LINK/V2-1 debugger and programmer. The STM32 Nucleo boards
come with the comprehensive free software libraries and examples available with the
STM32Cube MCU Packages, as well as direct access to the Arm® Mbed online resources

Nucleo board features are available at the www.st.com/stm32nucleo web page.
7. Develop the application using the available examples.
5.2 NUCLEO-L476RG bootloader limitations
Boot from system Flash memory results in executing bootloader code stored in the system
Flash memory, protected against write and erase. This allows in-system programming (ISP),
that is, flashing the STM32 user Flash memory. It also allows writing data into RAM. The
data come in via one of the communication interfaces such as USART, SPI, I2C bus, USB,
or CAN.
The bootloader version can be identified by reading the bootloader ID at the address
0x1FFF6FFE.
The STM32L476RGT6 part soldered on the NUCLEO-L476RG main board is marked with a
date code, corresponding to its date of manufacturing. STM32L476RGT6 parts with the date
code prior or equal to week 22 of 2015 are fitted with bootloader V 9.0, affected by the
limitations to be worked around, as described hereunder. Parts with the date code starting
from week 23 of 2015 contain bootloader V 9.2 in which the limitations no longer exist.
To locate the visual date code information on the STM32L476RGT6 package, refer to the
section “Package information” of the datasheet (DS10198) available at www.st.com. Date
code related portion of the package marking takes Y WW format, where Y is the last digit of
UM1724 Rev 14 11/68
UM1724 Quick start
67
the year and WW is the week. For example, a part manufactured in week 23 of 2015 bares
the date code 5 23.
The bootloader ID of the bootloader V 9.0 is 0x90.
The following limitations exist in the bootloader V 9.0:
1. RAM data get corrupted when written via USART/SPI/I2C/USB interface
Description:
Data write operation into RAM space via USART, SPI, I2C bus, or USB results in wrong or
no data written.
Workaround:
To correct the issue of the wrong write into RAM, download STSW-STM32158 bootloader
V 9.0 patch package from the www.st.com website and load ‘Bootloader V9.0 SRAM patch’
to the STM32, following the information in readme.txt file available in the package.
2. User Flash memory data get corrupted when written via CAN interface
Description:
Data write operation into user Flash memory space via CAN interface results in wrong or no
data written.
Workaround:
To correct the issue of the wrong write into Flash memory, download the STSW-STM32158
bootloader V 0.9 patch package from the www.st.com website and load ‘Bootloader V9.0
CAN patch’ to the STM32, following the information in readme.txt file available in the
package.
5.3 Hardware configuration variants
The board can be delivered with different configurations of the oscillator of the target
STM32. For all the details concerning high-speed configurations of the oscillator refer to
Section 6.7.1. For all the details concerning low-speed configurations of the oscillator refer

6.1 Pre-cut PCB
The STM32 Nucleo board is divided into two parts: ST-LINK part and target STM32 part.
The ST-LINK part of the PCB can be cut out to reduce the board size. In this case, the
remaining target STM32 part can only be powered by VIN, E5V, and +3.3V on the ST
morpho connector CN7, or VIN and +3.3V on ARDUINO® connector CN6. It is still possible
to use the ST-LINK part to program the main STM32 using wires between CN4 and SWD
signals available on the ST morpho connector (SWCLK CN7 pin 15 and SWDIO CN7 pin
13).
6.2 Embedded ST-LINK/V2-1
The ST-LINK/V2-1 programming and debugging tool is integrated into the STM32 Nucleo
board.
The ST-LINK/V2-1 makes the STM32 Nucleo boards Mbed Enabled™.
The embedded ST-LINK/V2-1 supports only SWD for STM32 devices. For information about
debugging and programming features, refer to the user manual ST-LINK/V2 in-circuit
debugger/programmer for STM8 and STM32 (UM1075), which describes in details all the
ST-LINK/V2 features.
The changes versus the ST-LINK/V2 version are listed below.
New features supported on ST-LINK/V2-1:
USB software re-enumeration
Virtual COM port interface on USB
Mass storage interface on USB
USB power management request for more than 100 mA power on USB
Features not supported on ST-LINK/V2-1:
–SWIM interface
Minimum supported application voltage limited to 3 V
Known limitation:
Activating the readout protection on ST-LINK/V2-1 target prevents the target
application from running afterward. The target readout protection must be kept
disabled on ST-LINK/V2-1 boards.
There are two different ways to use the embedded ST-LINK/V2-1 depending on the jumper
states (see Table 4 and Figure 6):
Program/debug the on-board STM32 (Section 6.2.2)
Program/debug an MCU in an external application board using a cable connected to
SWD connector CN4 (Section 6.2.4).

6.2.1 Driver
Before connecting the Nucleo-64 board to a Windows 7, Windows 8, or Windows 10 PC via
USB, a driver for ST-LINK/V2-1 must be installed. It can be downloaded from the
www.st.com website.
In case the STM32 Nucleo-64 board is connected to the PC before installing the driver, the
PC device manager may report some Nucleo interfaces as “Unknown”.
To recover from this situation, after installing the dedicated driver, the association of
“Unknown” USB devices found on the STM32 Nucleo-64 board to this dedicated driver,
must be updated in the device manager manually.
Note: It is recommended to proceed using a USB Composite Device, as shown in Figure 7.
Figure 7. Updating the list of drivers in Device Manager
6.2.2 ST-LINK/V2-1 firmware upgrade
The ST-LINK/V2-1 embeds a firmware upgrade mechanism for the in-situ upgrade through
the USB port. As the firmware may evolve during the lifetime of the ST-LINK/V2-1 product
(for example new functionality, bug fixes, support for new microcontroller families), it is
recommended to visit www.st.com website before starting to use the STM32 Nucleo board
and periodically, in order to stay up-to-date with the latest firmware version.

6.2.3 Using the ST-LINK/V2-1 to program and debug the STM32 on board
To program the STM32 on the board, plug in the two jumpers on CN2, as shown in red in
Figure 8. Do not use the CN4 connector as this could disturb the communication with the
STM32 microcontroller of the STM32 Nucleo board.

6.2.4 Using ST-LINK/V2-1 to program and debug an external
STM32 application
It is very easy to use the ST-LINK/V2-1 to program the STM32 on an external application.
Simply remove the two jumpers from CN2 as illustrated in Figure 9: Using ST-LINK/V2-1 to
program the STM32 on an external application, and connect the application to the CN4
debug connector according to Table 5.
Note: SB12 NRST (target STM32 RESET) must be OFF if CN4 pin 5 is used in the external
application.

6.3 Power supply and power selection
The power supply is provided either by the host PC through the USB cable, or by an
external source: VIN (From 7 V to 12 V), E5V (5 V) or +3.3V power supply pins on CN6 or
CN7. In case VIN, E5V or +3.3V is used to power the STM32 Nucleo board, using an
external power supply unit or auxiliary equipment, this power source must comply with the
standard EN-60950-1: 2006+A11/2009, and must be Safety Extra Low Voltage (SELV) with
limited power capability.
6.3.1 Power supply input from the USB connector
The ST-LINK/V2-1 supports USB power management allowing to request more than
100 mA current to the host PC.
All parts of the STM32 Nucleo board and shield can be powered from the ST-LINK USB
connector CN1 (U5V or VBUS). Note that only the ST-LINK part is power supplied before
the USB enumeration as the host PC only provides 100 mA to the board at that time. During
the USB enumeration, the STM32 Nucleo board requires 300 mA of current to the host PC.
If the host is able to provide the required power, the targeted STM32 microcontroller is
powered and the red LED LD3 is turned ON, thus the STM32 Nucleo board and its shield
can consume a maximum of 300 mA current, not more. If the host is not able to provide the
required current, the targeted STM32 microcontroller and the MCU part including the
extension board are not power supplied. As a consequence, the red LED LD3 remains
turned OFF. In such a case it is mandatory to use an external power supply as explained in
the next Section 6.3.2: External power supply inputs: VIN and E5V.
When the board is power supplied by USB (U5V) a jumper must be connected between pin
1 and pin 2 of JP5 as shown in Table 8.
JP1 is configured according to the maximum current consumption of the board when
powered by USB (U5V). JP1 jumper can be set in case the board is powered by USB and
maximum current consumption on U5V does not exceed 100 mA (including an eventual
extension board or ARDUINO® shield). In such a condition, USB enumeration always
succeeds since no more than 100 mA is requested to the PC. Possible configurations of
JP1 are summarized in Table 6.
Warning: If the maximum current consumption of the NUCLEO and its
extension boards exceeds 300 mA, it is mandatory to power
the NUCLEO using an external power supply connected to
E5V or VIN.
Note: In case the board is powered by a USB charger, there is no USB enumeration, so the led
LD3 remains set to OFF permanently and the target STM32 is not powered. In this specific
case, the jumper JP1 needs to be set to ON, to allow target STM32 to be powered anyway.

6.3.2 External power supply inputs: VIN and E5V
The external power sources VIN and E5V are summarized in Table 7. When the board is
power supplied by VIN or E5V, the jumpers configuration must be the following:
Jumper on JP5 pin 2 and pin 3
Jumper removed on JP1
Using VIN or E5V as external power supply
VIN or E5V can be used as an external power supply in case the current consumption of the
STM32 Nucleo and extensions boards exceeds the allowed current on USB. In this
condition, it is still possible to use the USB for communication, for programming or
debugging only, but it is mandatory to power supply the board first using VIN or E5V then
connect the USB cable to the PC. Proceeding this way ensures that the enumeration occurs
thanks to the external power source.
The following power sequence procedure must be respected:

1. Connect the jumper between pin 2 and pin 3 of JP5
2. Check that JP1 is removed
3. Connect the external power source to VIN or E5V
4. Power on the external power supply 7 V< VIN < 12 V to VIN, or 5 V for E5V
5. Check that LD3 is turned ON
6. Connect the PC to USB connector CN1
If this order is not respected, the board may be supplied by VBUS first then by VIN or E5V,
and the following risks may be encountered:
1. If more than 300 mA current is needed by the board, the PC may be damaged or the
current supply can be limited by the PC. As a consequence, the board is not powered
correctly.
2. 300 mA is requested at enumeration (since JP1 must be OFF) so there is a risk that the
request is rejected and the enumeration does not succeed if the PC cannot provide
such current. Consequently, the board is not power supplied (LED LD3 remains OFF).
6.3.3 External power supply input: +3.3V
It can be of interest to use the +3.3V (CN6 pin 4 or CN7 pin 12 and pin 16) directly as power
input for instance in case the 3.3V is provided by an extension board. When the STM32
Nucleo board is power supplied by +3.3V, the ST-LINK is not powered, thus the
programming and debug features are unavailable. The +3.3V external power source is
summarized in Table 9.
Two different configurations are possible when using +3.3V to power the board:
ST-LINK is removed (PCB cut) or
SB2 (3.3V regulator) and SB12 (NRST) are OFF.
6.3.4 External power supply output
When powered by USB, VIN, or E5V, the +5V (CN6 pin 5 or CN7 pin 18) can be used as an
output power supply for an ARDUINO® shield or an extension board. In this case, the
maximum current of the power source specified in Table 7 must be respected.
The +3.3V (CN6 pin 4 or CN7 pin 12 and 16) can be used also as power supply output. The
current is limited by the maximum current capability of the regulator U4 (500 mA max).

6.4 LEDs
The tricolor LED (green, orange, red) LD1 (COM) provides information about ST-LINK
communication status. LD1 default color is red. LD1 turns to green to indicate that
communication is in progress between the PC and the ST-LINK/V2-1, with the following
setup:
Slow blinking Red/Off: at power-on before USB initialization
Fast blinking Red/Off: after the first correct communication between the PC and
ST-LINK/V2-1 (enumeration)
Red LED On: when the initialization between the PC and ST-LINK/V2-1 is complete
Green LED On: after a successful target communication initialization
Blinking Red/Green: during communication with the target
Green On: communication finished and successful
Orange On: Communication failure
User LD2: the green LED is a user LED connected to ARDUINO® signal D13 corresponding
to STM32 I/O PA5 (pin 21) or PB13 (pin 34) depending on the STM32 target. Refer to
Table 11 to Table 23 when:
the I/O is HIGH value, the LED is on
the I/O is LOW, the LED is off
LD3 PWR: the red LED indicates that the STM32 part is powered and +5V power is
available.
6.5 Push-buttons
B1 USER: the user button is connected to the I/O PC13 (pin 2) of the STM32
microcontroller.
B2 RESET: this push-button is connected to NRST, and is used to RESET the STM32
microcontroller.
Note: The blue and black plastic hats that are placed on the push-buttons can be removed if
necessary, for example when a shield or when an application board is plugged on top of the
Nucleo board. This will avoid pressure on the buttons and consequently a possible
permanent target STM32 RESET.
6.6 JP6 (IDD)
Jumper JP6, labeled IDD, is used to measure the STM32 microcontroller consumption by
removing the jumper and by connecting an ammeter:
Jumper ON: STM32 microcontroller is powered (default).
Jumper OFF: an ammeter must be connected to measure the STM32 microcontroller
current. If there is no ammeter, the STM32 microcontroller is not powered.

6.7 OSC clock
6.7.1 OSC clock supply
There are four ways to configure the pins corresponding to the external high-speed clock
(HSE):
MCO from ST-LINK: MCO output of ST-LINK MCU is used as an input clock. This
frequency cannot be changed, it is fixed at 8 MHz and connected to
PF0/PD0/PH0-OSC_IN of the STM32 microcontroller.
The following configuration is needed:
SB55 OFF and SB54 ON
SB16 and SB50 ON
R35 and R37 removed
HSE oscillator on-board from X3 crystal (not provided): for typical frequencies and
its capacitors and resistors, refer to the STM32 microcontroller datasheet. Refer to the
AN2867 Application note for oscillator design guide for STM32 microcontrollers.The X3
crystal has the following characteristics: 8 MHz, 16 pF, 20 ppm, and DIP footprint. It is
recommended to use 9SL8000016AFXHF0 manufactured by Hong Kong X'tals
Limited.
The following configuration is needed:
SB54 and SB55 OFF
R35 and R37 soldered
C33 and C34 soldered with 20 pF capacitors
SB16 and SB50 OFF
Oscillator from external PF0/PD0/PH0: from an external oscillator through pin 29 of
the CN7 connector.
The following configuration is needed:
–SB55 ON
–SB50
OFF
R35 and R37 removed
HSE not used: PF0/PD0/PH0 and PF1/PD1/PH1 are used as GPIOs instead of clocks
The following configuration is needed:
SB54 and SB55 ON
SB16 and SB50 (MCO) OFF
R35 and R37 removed
There are two possible default configurations of the HSE pins, depending on the version of
the STM32 Nucleo board hardware.
The board version MB1136 C-01 or MB1136 C-02 is mentioned on the sticker, placed on the
bottom side of the PCB.
The board marking MB1136 C-01 corresponds to a board, configured as HSE not used.
The board marking MB1136 C-02 (or higher) corresponds to a board, configured to use
ST-LINK MCO as the clock input.

Note: For NUCLEO-L476RG and NUCLEO-L452RE the ST-LINK MCO output is not connected to
OSCIN to reduce power consumption in low power mode. Consequently, NUCLEO-L476RG
and NUCLEO-L452RE configurations correspond to HSE not used.
6.7.2 OSC 32 kHz clock supply
There are three ways to configure the pins corresponding to the low-speed clock (LSE):
On-board oscillator: X2 crystal. Refer to the Oscillator design guide for STM8S,
STM8A and STM32 microcontrollers application note (AN2867) for oscillator design
guide for STM32 microcontrollers.It is recommended to use ABS25-32.768KHZ-6-T,
manufactured by Abracon Corporation.
Oscillator from external PC14: from external oscillator through the pin 25 of CN7
connector.
The following configuration is needed:
SB48 and SB49 ON
R34 and R36 removed
LSE not used: PC14 and PC15 are used as GPIOs instead of low-speed clocks.
The following configuration is needed:
SB48 and SB49 ON
R34 and R36 removed
There are three possible default configurations of the LSE depending on the version of the
STM32 Nucleo board hardware.
The board version MB1136 C-01 or MB1136 C-02 is mentioned on the sticker placed on the
bottom side of the PCB.
The board marking MB1136 C-01 corresponds to a board configured as LSE not used.
The board marking MB1136 C-02 (or higher) corresponds to a board configured with
on-board 32 kHz oscillator.
The board marking MB1136 C-03 (or higher) corresponds to a board using new LSE crystal
(ABS25) and C26, C31, and C32 value update.
6.8 USART communication
The USART2 interface available on PA2 and PA3 of the STM32 microcontroller can be
connected to ST-LINK MCU, ST morpho connector, or to ARDUINO® connector. The choice
can be changed by setting the related solder bridges. By default, the USART2
communication between the target STM32 and ST-LINK MCU is enabled, in order to
support virtual COM port for Mbed™ (SB13 and SB14 ON, SB62 and SB63 OFF). If the
communication between the target STM32 PA2 (D1) or PA3 (D0) and shield or extension
board is required, SB62 and SB63 must be ON, while SB13 and SB14 must be OFF. In such
a case, it is possible to connect another USART to ST-LINK MCU using flying wires between
the ST morpho connector and CN3. For instance, on NUCLEO-F103RB it is possible to use
USART3 available on PC10 (TX) and PC11 (RX). Two flying wires need to be connected as
follow:
PC10 (USART3_TX) available on CN7 pin 1 to CN3 pin RX
PC11 (USART3_RX) available on CN7 pin 2 to CN3 pin TX

6.11 ARDUINO® connectors
CN5, CN6, CN8, and CN9 are female connectors compatible with ARDUINO® standard.
Most shields designed for ARDUINO® can fit the STM32 Nucleo boards.
The ARDUINO® connectors on the STM32 Nucleo board support the ARDUINO® Uno V3.
For compatibility with ARDUINO® Uno V1, apply the following modifications:
SB46 and SB52 must be ON,
SB51 and SB56 must be OFF to connect I2C on A4 (pin 5) and A5 (pin 6 of CN8).
Caution 1: The I/Os of STM32 microcontroller are 3.3 V compatible instead of 5 V for ARDUINO® Uno
V3.
Caution 2: SB57 must be removed before implementing ARDUINO® shield with VREF+ power being
provided on CN5 pin 8. Refer to Table 10: Solder bridges for details on SB57.
Table 11 to Table 23 show the pin assignment of each main STM32 microcontroller on
ARDUINO® connectors.

6.12 ST morpho connector
The ST morpho connector consists in male pin headers (CN7 and CN10) accessible on both
sides of the board. They can be used to connect the STM32 Nucleo board to an extension
board or a prototype/wrapping board placed on top or on bottom side of the STM32 Nucleo
board. All signals and power pins of the STM32 are available on ST morpho connector. This
connector can also be probed by an oscilloscope, logical analyzer or voltmeter.
Table 24 to Table 33 show the pin assignments of each STM32 on ST morpho connector.

7 Nucleo-64 boards information
7.1 Product marking
The sticker located on the top or bottom side of the PCB board shows the information about
product identification such as board reference, revision, and serial number.
The first identification line has the following format: ‘MBxxxx-Variant-yzz’, where ‘MBxxxx’ is
the board reference, ‘Variant (optional) identifies the mounting variant when several exist,
‘y’ is the PCB revision and ‘zz’ is the assembly revision: for example B01.
The second identification line is the board serial number used for traceability.
Evaluation tools marked as “ES” or “E” are not yet qualified and therefore not ready to be
used as reference design or in production. Any consequences deriving from such usage will
not be at ST charge. In no event, ST will be liable for any customer usage of these
engineering sample tools as reference design or in production.
‘E’ or ‘ES’ marking examples of location:
On the target STM32 that is soldered on the board (for illustration of STM32 marking,
refer to the STM32 datasheet “Package information” paragraph at the www.st.com
website).
Next to the evaluation tool ordering part number that is stuck or silk-screen printed on
the board.
Some boards feature a specific STM32 device version that allows the operation of any stack
or library. This STM32 device shows a ‘U’ marking option at the end of the standard part
number and is not available for sales.
In order to use the same commercial stack in his application, a developer may need to
purchase a part number specific to this stack/library. The price of those part numbers
includes the stack/library royalties.
The board reference for the STM32 Nucleo-144 boards is MB1136.
