Description M5Stack Mini Heart Rate Unit (MAX30100) Pulse Oximeter is a compact blood oxygen and heart-rate sensing unit built around the MAX30100 sensor. It combines red and infra red LEDs with a photodetector to support non-invasive pulse oximetry and heart-rate measurement in wearable, health-monitoring, and embedded sensing prototypes. The Heart Rate Unit communicates over I2C at address 0x57 and supports programmable sample rate and LED current settings, helping balance measurement performance and power consumption. Place a finger on the sensing area after the program starts to read pulse and blood oxygen data through an M5Stack controller. Product Status Notice This product is EOL (End of Life).
