Introduction

The MAXREFDES103# contains enables quick evaluation of our hardware and embedded firmware for heart-rate and SpO2 monitoring on a wrist-based platform to significantly shorten development time for custom fitness, health, and clinical applications.

The MAXREFDES103# platform includes the following key components

  • Micro board, which includes the MAX32630 microcontroller, MAX20303 power-management IC (PMIC), dual-mode Bluetooth, and 6-axis accelerometer and gyroscope
  • Sensor board, which includes the MAX86141 AFE, optical heart-rate sensor with one green LED, one red LED, one IR LED, two photodiodes, and MAX32664C biometric sensor hub with an embedded algorithm for heart rate and SpO2 monitoring
  • MAXDAP Pico Adapter board for use during a firmware upgrade for the micro board
  • Health sensor band enclosure and straps
  • Hardware design files, firmware, and software
