描述

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.

描述

Maxim Integrated brings the convenience of remote health monitoring to your fingertips. The modular architecture allows for a variety of systems to be assembled quickly and easily within a couple of minutes. The system flexibility stems from the FeatherWing® form factor that provides a plug-and-play interface by adding or removing desired sensors, enabling or disabling a particular sensor, and the frequency data transmission to an online dashboard. The system is built on a Maxim Integrated low-power microcontroller to ensure minimum power consumption for designs on the go.
