Could anyone tell me exact definitions of UART pins on Azteeg X5 mini WiFi? I have no connection using P0.30/P0.20 (works fine for my Smoothieboard 0X + RPi + Klipper) or P4.29/P4.28 (another option in menuconfig).
I vaguely remember users reporting issues with using UART on smoothie+Azteeg products (maybe azteeg wifi products). Maybe searching forums/google would yield results about what the issue more precisely is
