Re: No UART signal from ESP32-C3-Mini (Custom PCB)
I understand what you are saying, but before re-ordering a new board with the fixed RC circuit for the EN pin, I want to make sure there's no other issue in the board. I think that there could be something else, since there is a previous designed (printed on an FR4 substrate, while this one is on a ...

No UART signal from ESP32-C3-Mini (Custom PCB)
<t>Hello,<br/>
<br/>
I have this design for a custom PCB (attached the electrical schematics and the layout).<br/>
The PCB is a flex PCB, so it's really thin, with a stiffener below the ESP32.<br/>
<br/>
Unofrtunately, despite seeming to be powered on (the board draws about 14mA when powered, versus ...
