+The MacArthur HAT (Hardware Attached on Top) is a specialized expansion board designed for the Raspberry Pi, primarily used in marine and outdoor applications. It integrates various sensors, including GPS, 9-axis IMU (accelerometer, gyroscope, and magnetometer), barometer, and temperature sensors. This HAT enables the Raspberry Pi to collect comprehensive environmental and navigational data, making it ideal for marine electronics projects, weather stations, and IoT applications. Its compatibility with NMEA 2000 networks and Signal K platforms enhances its utility in modern marine systems, allowing easy integration with other onboard electronics and data-sharing capabilities.
