Figure 2. MAXREFDES101# block diagram.
This second-generation health sensor platform (a follow-on to the MAXREFDES100#) integrates a PPG 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 application code for heart-rate algorithm and AFE drivers (MAX32664)an embedded
heart-rate algorithm (MAX32664). Algorithm output and sensorraw data can be streamed through
Bluetooth® to an Android® application or PC GUI for demonstration, evaluation, and customized
development.
