ESP32-C3-Mini Not Running

[bixo-d]

Hi!

I have this ESP32-C3 board clone that have two usb-c connectors, a purple one. It has been working alright until today.

It stopped running the sketches. It communicates with the computer with both usb, that it means that the CH340 is alive and the ESP32 is alive, but it doesn't run my sketch. I uploaded the BlinkRGB that comes in the examples and it upload but it doesn't run either. There are no errors during the upload, the serial leds blink during the tx (both), but the rgb does nothing, just the sketches doesn't run anymore.

I'm using Arduino IDE and PlatformIO with the same results.

The difference between yesterday and today is that I transported the ESP between two different sites and in the box where other electronics that could have touched terminal or something. There where no powered devices in the box, so I believe that there is no chance of short circuit, but who knows.

Is there any external component that indicates the device to run that could be damaged during the transport? Here there is a lot of humidity so there no or too little static electricity.

Is there a way I can check the mode of the esp32? or the integrity of the bootloader? or any other idea i should check?

I'm including a picture of the product and some schematic of the circuit I found on the internet. The circuit in the schematic has little differences with the product, particularly in the voltage regulator. The other thing with the schematics is that the internals of the esp32 are exposed, but in reality are under the shield unaccesible.

Thanks in advance!

Make sure you plug into the "COM" port and USB-CDC is not enabled in the tool menu. Set Core Debug Level to verbose.
Turn on the Serial Monitor.
Add a Serial.println statement at the top of loop
Upload the code
If you get response on the console, but no colors, perhaps you damaged the led while moving.
