Power Pins

  • Vin - this is the power pin. This chip can handle 2.7V to 5V. 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 Logic Pins

  • SCL - this is the I2C clock pin, connect to your microcontroller's I2C clock line.
  • SDA - this is the I2C data pin, connect to your microcontroller's I2C data line.

Alert Pins

  • A1 - A4 - Alert 1 - Alert 4 output pins

Address Pin

  • ADR - Allows for setting I2C address
