integrating the ESP32 into my own PCB
Posted: Fri Mar 09, 2018 1:50 pm
Hey, I went have a little trouble integrating the esp32 into my circuit. I used this setup: [img]https://cdn.instructables.com/FOU/1WS0/ ... .LARGE.jpg

I managed to flash the device but I am ending up with this on the serial interface:
Is the reason because the power is not sufficient or just not stable? how do I fix this?

Is the reason because the power is not sufficient or just not stable? how do I fix this?
