MAXREFDES220

描述

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

The MAX30101 and the MAX32664 provide an integrated hardware and software solution for multiple finger-based applications. The MAX32664 firmware provides algorithm output.

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

Design files, firmware, and software are available for this reference design. The board is also available for purchase.
