Programming Jib for ESP32 WROOM Module

Postby astronomical » Thu May 25, 2017 4:27 pm

Hey there everyone,

Do any Pogo/ZIF programming jibs exist fir the ESP32 WROOM/S module?

I would like to program the module before I ever solder it onto my board to save on space. Since I would only use serial programming for the initial flash, I would only use the serial flash pins once. All future updates would be OTA. I would like to avoid breaking out and routing pins or access points for TX, RX, EN, GPIO0, etc if possible.

I have seen programming jibs for AVRs and ARMs. Does anything exist for the ESP32 WROOM/S modules? If not, I would happily build one, but how would I access such tiny pins without having soldering wires onto it?

Thanks!

The one from taobao doesn't have an auto reset circuit (or there's something wrong with it) even though it has the cp2102 on it.

Perhaps its just me, but solely relying on OTA is like asking for trouble imho. I'd definitely add a place for a pin header in the design, just to be sure that it is possible to restore a bricked item. You don't even have to fit it in production, but it is there when/if you need it. Just my 2 cents.
