There are only four pins that need to be connected to start using this sensor in a project. One for VCC, one for GND, and two data lines for I2C communication. This breakout board has built-in 4.7k pull-up resistors for I2C communication. If you’re connecting multiple I2C devices on the same bus, you may want to turn off these resistors.
