　　The MAX86150 is an integrated electrocardiogram, pulse oximeter, heart rate monitor sensor module. It includes internal LEDs, photodetector, and low-noise electronics with ambient light rejection. The MAX86150 helps ease design-in to mobile and wearable devices.

　　The MAX86150 operates on a 1.8V supply voltage with a separate power supply for the internal LEDs. Communication to and from the module is entirely through a standard I2C-compatible interface. The module can be shut down through software with near zero standby current, allowing the power rails to remain powered at all times.

　　The MAX86150 Evaluation System (EV system) provides a proven platform to evaluate the MAX86150 integrated photoplethysmogram (PPG) and 1-lead electrocardiogram (ECG) sensor module. The EV system consists of two boards that connect through header pins: a MAX32630FTHR microcontroller board and a MAX86150 evaluation kit (EV kit). The MAX32630FTHR houses a microcontroller with preloaded firmware, Bluetooth communication, and power management. The sensor board contains the MAX86150 module and two stainless steel dry electrodes for ECG measurement. The EV kit is powered by the included lithium ion battery, which is charged with a micro-USB cable.
