Measuring SpO
2
and Heart Rate
Using MAX32664C – A Quick Start Guide
UG6924; Rev 0; 6/19
Abstract
The MAX32664C is a variant of the MAX32664 sensor-hub family, which is specifically targeted
for measurement of SpO
2
and heart rate. Combined with the MAX86141 optical sensor and a 3-
axis accelerometer, it provides the sensor’s raw data, as well as calculated SpO
2
or heart-rate
data, to a host device through its I
2
C slave interface. This document provides step-by-step
instructions that enable a user to communicate with the MAX32664C and to calibrate, configure,
and receive measurement and monitoring data.
