Hello,
I have tested ESP32- C3-MINI-1 module thanks to ESP32- C3- DevKit- 1.
Very satisfied, I plan to use ESP32- C3-MINI-1 module on my futures PCB designs.
When my PCB manufacturer will reference some ESP32- C3-MINI-1 module, is there a firmware pre-programmed?
Does that default firmware/ bootloader allows me to upload my Arduino operation via uart ( RX0/ TX0, or make in USB Serial) like I do with my ESP32- C3- DevKit- 1 with Arduino IDE?
Or do I need to firstly flash a bootloader through some JTAG or SPI?
Thank you!

There either is no firmware in flash, or a testing or AT firmware that is likely not useful. That doesn't matter, however, because: Every ESP32 (including C3, S3, ...) has a hardcoded, unchangable and un-erasable ROM that contains a bootloader that allows you to do these things (as long as you don'tRead more
There either is no firmware in flash, or a testing or AT firmware that is likely not useful. That doesn’t matter, however, because: Every ESP32 (including C3, S3, …) has a hardcoded, unchangable and un-erasable ROM that contains a bootloader that allows you to do these things (as long as you don’t set the efuse to disable them). So whatever firmware the module comes with, you will be able to reprogram it using UART or USB.
