Debug Console
Connect to the debug console on connector J32 (pins 1-2).
UART 232
On J32 connector close TX with RX (pins 11-12) and use minicom on ttySTM1 to test local echo.
UART 485
Tested /dev/ttySTM2 (connector J31) with another RS485 device. Configure minicom:
Configure the Serial Port Setup as shown:
Wi-Fi PCIe
Tested using Intel Dual Band Wireless-AC 8265 Wi-Fi module (M.2 key E) on connector J14. Drivers load at boot time, or manually:
