Im have a project with a PCB assembly that uses the ESP32 WiFi and Bluetooth. Everything seems to be working okay but at a random time the ESP32 will stop all functions until the PCB assembly is unplugged and re-plugged in. Im not sure if this is related to the ESP32 or something else, but if anyone has any experience with something along these lines any help would be greatly appreciated.
The PCB assembly controls a fridge by turning a relay on/off based on a temperature input. The board is run off of a 120VAC to 12VDC power supply. Is there anyway that the power supply could get a low voltage and shut the chipset down?
