Esp32 module with Custom Board.

[Alberk]

I have a question. If on my custom board I don't want to have USB to UART chip (CP2002). Can I just do the following for Pin EN and GPIO0?

Thank you.

That should work but how do you plan on flashing the module? I generally bring these plus GND and RXD/TXD to a connector (even if unpopulated) so that in a pinch the board can be re-flashed.

Thank you for the reply. I plan to have the EN, GPIO0, VCC, GND exposed as diagnostic pins (for firmware flashing). this will save one USB/UART chip on the custom board.
