Setup Pypilot motor controller with MacArthur HAT

[Sailoog]

Glad you found the RJ45 pinout. Both solutions seem functional, but we will soon propose a more reliable one.

Lazzz, is UART1 working right with pypilot?

For the record:

GPIO0 and GPIO1 (pin 27 and 28) are UART1 in Rpi5 but UART2 in Rpi4.
