#47515 Hello,

I have two NodeMCU v0.9 that are not responding anymore.

For both I can see them being recognized as a serial device but there is no response from the ESP.

I have measured the connections and there is 3.3v on the appropriate pins.

The first one died after unplugging and re-plugging. There is no light being flashed, no blue, no red.

The second died a bit later in a different setup and is just flashing the red light when connection the reset pin to GND.
This one is also becoming hot on the ESP module.

Both aren't recognized by the ESPtool and the NodeMCU flasher.

Any ideas how to resurrect them would be appreciated.
