MAXREFDES101#: Health Sensor Platform 2.0

MAXREFDES101

Reference Design Disclaimer See the  Important Notice and Disclaimer  covering reference designs and other Maxim resources.

Description

The MAXREFDES101# is a unique evaluation and development platform in a wrist-worn wearable form factor that demonstrates the functions of a wide range of Maxim’s products for health-sensing applications. This second-generation health sensor platform (a follow-on to the MAXREFDES100#) integrates a PPG analog-front-end (AFE) sensor (MAX86141), a biopotential AFE (MAX30001), a human body temperature sensor (MAX30205), a microcontroller (MAX32630), a power-management IC (MAX20303), and a 6-axis accelerometer/gyroscope. The complete platform includes a watch enclosure and a biometric sensor hub with an embedded heart-rate algorithm (MAX32664). Algorithm output and raw data can be streamed through Bluetooth® to an Android® app or PC GUI for demonstration, evaluation, and customized development.

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

Introduction

The MAXREFDES101# is the second generation in our family of health sensor development platforms. Like the previous generation, MAXREFDES100#, the MAXREFDES101# enables quick evaluation of our portfolio of wearable products to significantly shorten the development time for custom fitness, health, and clinical applications.

The MAXREFDES101# 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 LEDs and two photodiodes, MAX30001 ECG sensor, MAX30205 body temperature sensor, and MAX32664 biometric sensor hub with an embedded heart-rate algorithm
  • Pico adaptor board for use during a firmware upgrade for the micro board only
  • Watch enclosure
  • Hardware design files, firmware, and software
