ESP32 Forum

Why would powering the 5v pin with a wall plug in 5v micro usb not work? In other words I have plugged in 5v from the wall and it doesn’t work correctly.

I assume that when using the external power supply
1) You do not have a USB connection?
2) Your eternal supply can supply enough current to the ESP-32? I would allow for 0.8A

Thank you for the reply Spile,

Two things might be the issue. My power supply is rated 2.5 amps

Also
The power supply is just sitting on the breadboard. No soldering

Whenever I plug another power supply into the usb breakout I get different output. One is almost nothing and the other streaming gibberish.

I think I will buy a soldering iron today

Here are a couple pictures of my setup

I guess I need to get a soldering iron and solder the breakout board. I'm 99% sure thats the problem

was wanting to go for a cheap option but I am fine with this
