Introduction

The MAXREFDES104# is the second generation in our family of health sensor development platforms. Like the previous generation, MAXREFDES101#, the MAXREFDES104# enables quick evaluation of our portfolio of wearable products to significantly shorten the development time for custom fitness, health, and clinical applications.

The MAXREFDES104# platform includes the following key components

  • Micro board: Includes the MAX32666 host microcontroller, MAX32670 algorithm hub, MAX20360 power management IC (PMIC), dual-mode Bluetooth, and flash storage
  • Sensor board: Includes the MAX86176, ECG + PPG AFE, optical heart-rate sensor with three LEDs (Green, Red and IR), and three photodiodes, ECG electrodes, and 3-axis accelerometer
  • Sensor board 2: Includes flex cable with the MAX30208 body temperature sensor
  • 3D-printed enclosure
  • BLE dongle
  • Design files, hardware and software
