Ok, i did some measurements and found out, that esp´s gpio2 is connected to the TX pin of the board. The U0TXD isn´t connected to any pins. and the U0RXD is connected to the RX Pin of the board.

Is there a way to get repl´s tx on gpio2 and leave rx on U0TXD ?

I would like to bring up my question cause i really like the h801 boards. My solution so far is to solder a very thin wire to a via on the board. As i just killed some boards i would like to know if i can build a custom firmware which uses gpio2 as default tx pin?
Using C i can use serial2 to communicate over this pin but i didn´t find a solution to use it on mp.
