I want to connect the “Pixawk Cube” with a “Raspberry Pi” by “UART”.
The main purpose is to use the RTPS/ROS2 interface after the connection being established.
Which psychical ports can I use for the UART protocol? There is no explicit “UART port” like SPI or I2C in the picture below. Telemetry 2, GPS 2? Which cable should I use to connect the two devices and which pins from the port should I choose since UART just needs 3 pins?
Thanks by your attention!
