Datasheet

I2C Pins

SCL - I2C clock pin, connect to your microcontrollers I2C clock line.

SDA - I2C data pin, connect to your microcontrollers I2C data line.

INT and ADDR Pins

A is the I2C Address select pin. By default this is pulled down to ground with a 10K

resistor, for an I2C address of 0x1C. You can also connect it to the 3Vo pin for an

address of 0x1D

I1 and I2 are the Interrupt #1 and #2 signal pins. These pins are for more advanced

usage, where you want to be alerted by the chip say when data is ready to read, or if it

detects a large motion. We don't have direct support in the example Arduino library for

these pins, so please check the datasheet for the I2C commands
