ESP32 Thing plus Wroom not recognized by device manager

Development Boards ESP32

I ordered an Esp32 thing plus previously, and was so happy with it that I ordered 3 more. Unfortunately, one of them does not work. Neither the Arduino IDE, nor device manager recognizes it as a com port when plugged in to USB. Also, unlike the other 3, the yellow charge led on this one flashes nonstop when plugged in.

I believe it is a problem with the board rather than user error, because if I unplug it and plug any of my other three identical products in, device manager and Arduino IDE both recognize them just fine.

Greetings. Thanks for posting on the forums.

Looking at the schematic and the datasheet for the MPC73831 I don’t think a blinking status LED is proper behavior and could indicate a short of some kind I believe.

I think you should file an RMA ticket and we can get you taken care of. You can submit a return ticket here:

I hope this helps. I look forward to assisting you soon.
