Announcing: Moitessier HAT


  • High-sensitivity (better than -114 dBm) dual channel AIS receiver with SMA antenna connector.

  • High-performance GNSS receiver with integrated patch antenna and external antenna support via BNC connector.

  • Compass, heel and trim from gyroscope, accelerometer and magnetometer sensors (IMU).

  • Barometric pressure.

  • Standalone usage or in combination with Raspberry Pi (). Sensors are directly accessible via Raspberry Pi. Standalone usage requires 3.3V power supply and sensors are controlled by the HAT’s microcontroller

  • Fully compatible with Raspberry Pi models supporting 40-pin IO header.

  • Data communication via SPI (AIS, GNSS and meta data) and via I2C (sensor data). Data accessible via device driver and device file.

  • Supports ID EEPROM and automatic device tree loading

  • 3 status LEDs (AIS status, GNSS status, error)

  • Full OpenPlotter compatible. Plug and play.
