VIN is the power pin. You can connect it to 3.3V or 5V output from your Arduino.
SCL is the I2C clock pin, connect to your Arduino’s I2C clock line.
SDA is the I2C data pin, connect to your Arduino’s I2C data line.
INT The MAX30100 can be programmed to generate an interrupt for each pulse. This line is open-drain, so it is pulled HIGH by the onboard resistor. When an interrupt occurs the INT pin goes LOW and stays LOW until the interrupt is cleared.
IRD The MAX30100 integrates an LED driver to drive LED pulses for SpO2 and HR measurements. Use this if you want to drive the IR LED yourself, otherwise leave it unconnected.
RD pin is similar to the IRD pin, but is used to drive the Red LED. If you don’t want to drive the red LED yourself, leave it unconnected.
GND is the ground.
