Pinouts

Power Pins:

Vin - this is the power pin. Since the sensor chip uses 3-5 VDC. To power the board,

give it the same power as the logic level of your microcontroller - e.g. for a 5V micro

like Arduino, use 5V

GND - common ground for power and logic

I2C Control-Side pins:

SCL - this is the I2C clock pin for the chip itself, connect to your microcontrollers I2C

clock line.
