This repository contains a breakout board for the 9-DOF Inertial Measurement Unit (IMU) from TDK, ICM-20948 (data sheet). The i2c communication pins and the interrupt pin has external connection. The board is designed for 3.3v power supply, as the IMU requires 1.8v IO-levels there is a voltage level translator that translate IO-levels to/from the supply voltage. As the voltage level translator contains internal pull up resistors, there is no need to have extra pull up resistors on the IO-lines.

I have done some initial tests of this board and it seems to work just fine. I have also done an Arduino library for getting the data out.
