MAXREFDES220#: Finger Heart Rate 
and Pulse Oximeter Smart Sensor with 
Digital Signal Processing 

MAXREFDES220# System Board 

  

The MAXREFDES220# reference design provides everything you need to quickly 
prototype your product to measure finger-based heart rate and blood oxygen saturation 
level (SpO2). 

The MAX30101 and the MAX32664 provide an integrated hardware and software 
solution for multiple finger-based applications. The MAX32664 firmware provides digital 
signal processing to process the data. The reference design also includes a tri-axis 
accelerometer to compensate for motion artifacts. 

A MAX32630FTHR is provided to emulate a host system for easy development. 

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