Does anyone know how to resolve this error? My card presented this error when I upload a sketch, I suspect I burned it.
A fatal error occurred: Failed to connect to ESP32: Timed out waiting for packet header
A fatal error occurred: Failed to connect to ESP32

Is this document help you?
No! The AP2112 3.3V is getting very hot.
@sauloaislan20 did you manage to come up with a working solution for your problem? I am facing a similar problem uploading to my Lora-V2. The first sketch uploaded without any problems, but I cannot upload any other sketch after that.
