This is the Inertial Measurement Unit (IMU) recommended for OpenPlotter. Adding an IMU to OpenPlotter you can get heading, heel and trim data. It is a perfect complement to the MacArthur HAT. Shipped with pins soldered as seen in the photo.
This is a breakout board for the TDK InvenSense ICM-20948 9-axis IMU.
