Hello!
I have built a custom board with esp32-C3 mini,
I have managed to change the console to USB and everything works correctly,
but I can't get to use UART0 for a RS-485 max3485 converter, I use the example of echo-rs485 and nothing
tx-- GPIO20
rx--GPIO21
de/re--GPIO04
what am i missing?
Thanks!
