- MAXREFDES105# ($283.55) EV Kit
Description
The MAXREFDES105# is a wrist-worn wearable form factor that demonstrates the high sensitivity and algorithm processing functions for health-sensing applications. This health sensor band platform includes an enclosure and a biometric sensor hub with an embedded algorithm for heart rate and SpO2 (MAX32664C) which processes photoplethysmography (PPG) signals from the analog-front-end (AFE) sensor (MAX86174A). Algorithm output and raw data can be streamed through Bluetooth® to an Android® app or PC graphical user interface (GUI) for demonstration, evaluation, and customized development.Features & Benefits

Details Section
The MAXREFDES105# enables quick evaluation of hardware and embedded firmware for heart rate and SpO2 monitoring on a wrist-based platform which significantly shortens development time for custom fitness, health, and clinical applications. Figure 3 shows the system diagram of MAXREFDES105#.
The MAXREFDES105# platform includes the following key components:
- Micro board, which includes the MAX32630 microcontroller, MAX20303 power-management integrated circuit (PMIC), dual-mode Bluetooth, and 6-axis accelerometer and gyroscope.
- Sensor board, which includes the MAX86174A AFE, optical heart-rate sensor with one green light-emitting diode (LED), one red LED, one infrared (IR) LED, two photodiodes, and MAX32664C biometric sensor hub with an embedded algorithm for heart rate and SpO2 monitoring.
- MAXDAP-TYPE-C board for use during a firmware upgrade for the micro board.
- Health sensor band enclosure and straps.
- Hardware design files, firmware, and software.
