Hi, I purchased a couple of ESP32- C3 mini modules for a design. The modules are being mounted on the PCB board, I tried to flash/ program them for the application using a customized board (simplified schematic of esp32- c3 dev- board). The issue is that the system is unable to communicate with the module. I also replaced the module on an esp32-c3-mini dev board with the purchased one but still facing the same issue with the flashing. The question is that

Whether the esp32- c3 modules, in the market, are needed to be pre-programmed prior to the flashing process?

How I can flash the modules?

Any help comment/ guide will be appreciated!

Best Regards,

Alex

    Hello,

    I just spent quite a bit of time figuring out why I could not upload to my own boards, so I appreciate what you are experiencing.
    The ESP32- C3- Mini modules don’t need to be preprogrammed. You can write firmware to them directly using esptool.py
    I programmed mine using the Arduino IDE, which uses esptooly.py under the hood.
    Still, we might be suitable to help, If you share what your custom programming board looks like.

    Thank You & Regards
