Programming ESP32 Custom Board

Postby tmiranda » Wed Oct 03, 2018 4:17 pm

Hi guys,

I'm in the process of developing my own ESP32 custom board and I'm wondering which is the cheapest way to program it.

I have a DevKitC V4 and althought I would like to use the USB - UART converter on my own board, it will get expensive since I'll need an embedded converter chip on my board, so I'm looking for other options.

Should I just leave TX/RX pins exposed and use an outside board?

Thanks in advance.

The way I usually do it is to have a header with gnd/txd/rxd/io0/reset on it available. You can put an external programmer (like the esp-prog) on that header and program stuff that way.
