3. Important Design Considerations
3.1 PWR_ON Signal
To conserve power, the HL7588 does not automatically startup when power is
applied. The baseboard design must supply a means to assert the PWR_ON
signal for the specified time (at least 25 msec) and then released to startup the
module. After asserting the PWR_ON signal, software must wait for VGPIO to
assert before attempting to communicate with the HL7588. To make module
automatically start when power is applied, tie PWR_ON signal to GND
permanently. See Sierra Hardware User Guide for additional details regarding
the PWR_ON signal.
3.2 Power Supply Requirements
The module will regularly consume high amounts of current on the Main Power
Supply (VCC), up to 1.5A during active transmits and receives. The baseboard
power supply should be designed to support peak currents up to 2 Amps. A
100uF capacitor should be placed near the VCC pin on the module to ensure
ample energy is available, with a low inductance path to the VCC pin. For
example power supply designs, there are multiple references available. See the
NimbeLink Skywire Development Kit schematic for a switching regulator
example.
3.3 Serial Communications
The HL7588 can communicate over UART and/or USB. Design should
implement one or both serial interfaces to be able to send commands to the
modem.
3.4 LED
The Skywire has an on board LED D1 connected to HL7588 on GPIO10. This
LED can be asserted by software by issuing an AT command.
AT+KGPIO=10,1 //Turn on LED
AT+KGPIO=10,0 //Turn off LED

3.5 FOTA
LTE networks are constantly being updated, improved, and enhanced with new
features. As a result, carriers are making frequent network changes. Most will
not negatively affect devices connected to those networks, but occasionally an
update will prevent an unprepared device from re-connecting to the network
permanently.
To account for these future changes, FOTA (Firmware over the Air) capability is
being added to all cellular modules by each module manufacturer, and
NimbeLink supports this functionality in the Skywire family of embedded
modems. However, there is often a requirement to implement support for this
FOTA functionality in your device firmware.
As a developer using the Skywire modem, it is required that your device firmware
plan to accommodate FOTA updates after deployment. Failure to do so may
result in interruption of your device's cellular connectivity if the carriers implement
a network change. If the device can no longer access the network, FOTA cannot
be used to resolve the situation after the fact. The only way to restore
connectivity will be physical access to the device to perform the updates directly
on the device.
FOTA Instructions are available by contacting Nimbelink's product support team
at product.support@nimbelink.com.

4. Mounting Guidelines
The Skywire embedded cellular modem supports multiple connection methods,
the two primary methods are board to board connectors and soldering directly to
the baseboard.
4.1 Board to Board connectors approach
The Skywire interface calls for two, 10 pin, 2mm pitch female receptacles.
There are many connector manufacturers that can be used; below is one readily
available product:

4.2 Solder to Board connection approach
The module can be soldered directly to a PCB. The PCB should be designed
with two rows of ten, 0.8mm plated thru holes spaced 2mm apart. The two rows
should be 22mm apart. See drawing for recommended footprint. Measurements
are in millimeters. U.FL locations are marked with circles, X1 and X2 on top side
