Expansion Board for the MAX30101

Please check latest availability status for a specific part variant.


The MAX30101WING board is a rapid development board designed to quickly develop application firmware for the MAX30101 pulse oximetry sensor. The MAX30101WING contains the MAX14750A power management IC (PMIC) that supplies a +1.8V power rail (1V8) to the MAX30101 along with a programmable +2.5V to +5V rail (VLED) to drive the MAX30101 internal LEDs. The board is compatible with +1.8V and +3.3V logic (VIO), selectable through jumper JP1. The ZIF Flat Flexible Cable Connector allows integration of the MAX30205EVSYS, which features the MAX30205 silicon-based human body temperature sensor. The board seamlessly integrates with the MAX32630FTHR to enable rapid prototyping and development.
