Raspberry Pi just got even easier.

This just out from the Openplotter guys -
Introducing OpenPlotter hats!!!

A 'hat' board to plug into your Pi -

Features
2 channels Automatic Identification System (AIS) receiver.
Global Navigation Satellite System (GNSS) receiver. Built-in or external antenna.
IMU sensor.
Pressure sensor.
Temperature sensor.
Humidity sensor.
100% OpenPlotter compatible.
It also works standalone (no Raspberry connection).
State of development: Production.

Sounds very interesting, Openplotter must be the most integrated "all in one box" boat nav & monitoring software around at the moment.

A few more details out, hoping to be available end Jan they say.

Features
Standalone usage or in combination with Raspberry Pi (standalone usage requires 3.3V power supply).
Fully compatible with Raspberry Pi models supporting 40-pin IO header.
High-sensitivity dual channel AIS receiver with SMA antenna connector.
High-performance GNSS receiver with integrated patch antenna and external antenna support via BNC connector.
3 status LEDs.
Barometric pressure, humidity, temperature, gyroscope, accelerometer and magnetometer sensors. Sensors
are directly accessible via Raspberry Pi. In standalone mode the sensors are controlled by the host micro-controller.
IO headers to interface with spare GPIOs of the Raspberry Pi.
UART signals of Raspberry Pi available on 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 driver loading.
100% OpenPlotter compatible.

So by the looks of things it *could*be hacked to work with a pc/Mac though given the low power and cost of a Pi would it be worth the bother? Run headless and wifi all the data.

Could be a very handy gps/ais/compass/nav machine for delivery skippers. View on a tablet.
