MAX30003WING Expansion Board
General Description
The MAX30003WING is an expansion board designed
to help engineers and students alike to rapidly prototype
ECG applications for wearables using the MAX30003
biopotential analog front end. The form factor is a small
0.9in by 2.0in dual-row header footprint that is compat-
ible with breadboards and featherboards from Maxim
and Adafruit®, as well as additional expansion boards
called wings. Two grove connectors and a 6-pin Pmod™
connector are also included for additional connectivity to
popular development boards offered by Seeed Studio®
and Digilent®.

MAX30003WING Expansion Board
Detailed Description
The MAX30003WING expansion board is designed to
provide a compact rapid development platform for the
MAX30003 biopotential AFE. A 3.5mm jack has been
provided for prototyping with ECG leads that support this
interface. Two 4-pin grove connectors allow for integra-
tion of additional I2C and UART sensors from the Seeed
Studio Grove ecosystem. The dual inline pinout and
form-factor for this board are based on the Adafruit feath-
erboard series, and it is intended to be compatible with
many of their boards, but it is not guaranteed to work with
all of them.
Firmware Development
The simplest way to develop firmware for the MAX3003WING
is through the Mbed™ development site. At the Mbed site,
import examples into the online IDE, then edit, compile, and
load them into the Mbed-compatible featherboard without
installing any software. Go to https://os.mbed.com/plat-
forms/MAX32620FTHR/ to get started programming with
the MAX32630FTHR now. To support software develop-
ment with the MAX30003, an example library has been
developed and can be found at the following link: https://
os.mbed.com/teams/MaximIntegrated/code/MAX30003/.
Additionally, the two demo programs have been devel-
oped to expedite prototyping. The MAX30003WING_
Demo_Debug program notifies the user that there
has been an interrupt, calculates heart rate, displays
the status register, FIFO data, and ETAG result. The
MAX30003WING_Demo_Debug program can be found at
the following link: https://os.mbed.com/teams/Maxim-
Integrated/code/MAX30003WING_Demo_Debug/. The
MAX30003WING_Demo_QRS program serially streams
FIFO data to be plotted by a serial plotter of the users
choosing. The MAX30003WING_Demo_QRS program
reproduces the recorded QRS complex and can be found
at the following link: https://os.mbed.com/teams/Maxim-
Integrated/code/MAX30003WING_Demo_QRS/. For
information on how to start using the MAX30003WING,
refer to the Application Note 6556: How to Interface the
MAX30003WING ECG AFE with the MAX32630FTHR
located in the Design Resource tab of the product page.
