- It uses standard I2C compatible communication interface, and can transmit the collected values to single-chip computer for heart rate & oxygen calculation.
- It can effectively eliminate the external and internal light resistance and has reliable performance.
- It can shut down the module through software ,the standby current is close to zero, and the power supply can always maintain the power supply state.
- It integrates a red LED and an infrared LED, photo detector, optical devices, and low-noise electronic circuit with ambient light suppression.
- VIN: Main power input 1.8V-5V
- 3-bit pad: I2C bus pull up level, you can choose 1.8V or 3.3V according to the pin master voltage.
- SCL: I2C bus clock
- SDA: Connected to the I2C bus data
- INT: MAX30102 chip interrupt pin
- RD: MAX30102 chip’s RD LED grounding terminal, generally doesn’t need to connect.
- IRD: MAX30102 chip’s IR LED grounding terminal, generally doesn’t need to connect.
- GND: grounding wire.
