Note: Due to quality issues with our supplier, we currently do not stock the IMU module. We recommend to get an ICM-20948 module from Adafruit, Sparkfun (US) or Pimoroni (UK), which can be connected to the MacArthur HAT through the QWIIC connector.
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.
