After a few years of developing software for OpenPlotter, we have identified exactly what we need in terms of hardware to achieve our goals and the result is the MacArthur HAT (Hardware Attached on Top), an add-on board for Raspberry Pi running OpenPlotter. With this HAT we want to get the fully open-source boat to free ourselves from dependence on big companies and make our boats more respectful with the environment.
OPTIONAL: Power module for MacArthur HAT
OPTIONAL: ICM-20948 IMU module
