Re: Custom PCB + Wroom 32 crashes using Arduino-ESP32 Wifi Library
Thanks for all the suggestions. I found adding a 100uF electrolytic capacitor allows the system to work. I have some 600mA LDO's on order, which I am hopeful will allow me to remove the cap.

Custom PCB + Wroom 32 crashes using Arduino-ESP32 Wifi Library
I've built a custom PCB designed to use the ESP32 WROOM. During the assembly and validation of the board I've been using example arduino programs to make sure the esp32 is running correctly. Currently, I'm having a problem with running wifi examples on my board. When I flash the WiFiScan example, I ...
