Debug Console Voltage

I followed the instructions for setting up the debug console [1] and I am not seeing any output at all on the debug console.

I’m using a CH340G based USB UART that supports 1500000 baud [2]. This UART works for me on my Pine64 Rockpro64. It has two voltage settings; 3.3 and 5 volts. For Pine64 it needs to be 3.3 or it will fry the board. What voltage is correct for the Rock Pi N10 debug console?


I fixed this myself. This USB UART works fine in 3v3 mode. The correct setup is:
UART TX <–> GPIO RX pin 10
UART RX <–> GPIO TX pin 8
