Product Detail

The MAX30003WING2 evaluation kit demonstrates the use of the MAX32663A MCU as an ECG sensor hub. The MAX32663A runs advanced ECG algorithms provided by B-Secur, which transforms raw ECG data collected from the MAX30003 analog front end (AFE) into simple, high-level information which is then communicated to the MAX32620FTHR host processor through the I2C interface. The EV kit is accompanied by PC software, which allows easy evaluation of the ECG algorithms.

The kit includes the following items:

  • MAX30003WING2# Circuit Board
  • MAX326325PICO JTAG Debugger/Programmer
  • MAX32620FTHR Feather Board
  • Micro USB Cables
  • SWD Cable


  • Fitness Monitors
  • Industrial Sensors
  • IoT
  • Optical Modules: QSFP-DD, QSFP, 400G
  • Portable Medical Devices
  • Sports Watches
  • Wearable Medical Patches
