GPIO1 as output

#1 Post by hemant » 30 Mar 2020, 18:06


I would like to use the ESP01 GPIO1 as output, so i can control something using GPIO1.
Would that be possible and if yes how would the wiring look like.

I currently have GPIO3 as input using GND and RX, if I want TX as output would i use GND and GPIO1 (TX) any resistors required.
I understand the impact of serial when using TX.
