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!
