Win'10 Can't see esp32 C3 SuperMini

Hello everyone! :-)

Some time ago, I bought this board (esp32 C3 SuperMini) - but I still can’t start it - it is constantly “updating” in the Windows device manager every second (I don’t know how to call it more correctly).

I'm using arduino ide for flashing. I found a sequence of steps on the Internet that could help: https://community.platformio.org/t/how- ... rmio/36042 - but it didn't help me.

The board is very interesting and I would be glad if you could help launch it! As I understand from many questions on the Internet, this problem occurs in 100% of users who have just started working with it.

So, how to properly start working with it (flash etc.), could you describe in detail the sequence of steps?

Thank you in advance!

Possibly you need to put the device into download mode manually for the first flash. If the board has a 'boot' button, hold that while plugging it in; if not, ground GPIO9 and plug it in.

I assume this is the sort of mini device that only has a direct USB connection. In addition to the boot button as suggested above, you will want the following settings in Arduino IDE. Note that I consider these devices very poor for developing code, since it takes ~200ms for the USB CDC connection to establish. If your device is crashing within the first few milliseconds due to a misconfigured peripheral/pin, you will not be able to see the error before the reboot loop starts.
