Weird issue with breakout boards

Postby instantasset » Fri Mar 21, 2025 1:12 am

I have an esp32-wroom devkit c that works as intended. However, when I try to install it into a breakout board made for this dev kit, it enters an endless watchdog timer loop when I apply power (usb-c).

If I power the esp32 first, then install it into the breakout board, the esp32 functions correctly. If I install it, then power it up it malfunctions? I have tried 3 different breakout boards made by different companies and have the same result. Can anyone help me understand whats happening?

Code: Untitled.cpp Select all

Can you post the specific log that is generated when the ESP32 is in the situation where it resets because of the watchdog timeout? Also, just to confirm: aside from the devkit, the breadboard is empty, right?
