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.
