Скачать или смотреть raspberry on a boat #7: OpenPlotter (2/2) External sensors (I2C, USB, UART), pypilot, Signal K, GPS

Sailboats are expensive. If you own an older boat, it is mainly the accessories.
The Raspberry Pi mini computer is cheap and powerful. With some extra hardware, it can take over several tasks on a boat, like acting as a wireless access point, providing the plotter charts and software, collecting AIS information or multiplexing NMEA 0183 data.

This is part #7: In our second part of "OpenPlotter" we are connecting some external sensors, like a BME280 for barometric pressure, a MPU-9250 for pitch, roll (accelerometer) and yaw (compass) and a USB GPS VK-162 for our position (and accurate time).
We take a look at Signal K, additional to our existing KPLEX NMEA 0183 server, we add some dashboard widgets to OpenCPN and we take a look at pypilot for auto-steering.

Let's go!
