Description

The MAXREFDES104# is a unique evaluation and development platform in a wearable form factor that demonstrates the functions of a wide range of Maxim’s products for health-sensing applications. This third-generation health sensor platform (an advancement of the MAXREFDES101# Health Sensor Platform 2.0) integrates a two-in-one PPG + ECG analog-front-end (AFE) sensor (MAX86176), a human body temperature sensor (MAX30208), a microcontroller (MAX32666), a power-management IC (MAX20360), and a 3-axis accelerometer. The complete platform includes a 3D-printed enclosure and a biometric algorithm hub with an embedded heart-rate, oxygen saturation and ECG algorithms (MAX32670). Algorithm output and raw data can be streamed through Bluetooth to a PC GUI for demonstration, evaluation, and customized development.

Design files, hardware and software can be found under the Design Resources tab. The board is also available for purchase.

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
