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.
