1. S3 board MUST work with power supply, can you change to DC12V? can't only work with USB-C cable. the USB not power for the PCB.

2. do you have hold on the S2 button on the photo?

right step is:

1. power off S3 board.
2. hold on S2 button (not release your finger)
3. power on S3 board.
4. release your finger.
5. connect USB-C cable to your computer.

Yes, I am using the correct button.

I have many similar devices. The boards are faulty.

The spec says 9-24V not 12V specifically. 9-24V See screenshot.

my means , you can test with DC12v power . if you have tried different usb-c cable also can't work.
tell us your order number, where you buy from, we will check then feedback to you. maybe need replace ESP32-S chip.

do you have a BIN file want to download to S3 board, if YES, you can post at here, i can have a test. your board we have tested then re send to you. i don't know why you can't download by USB-C.

There's no point in testing my bin file.

I still cannot get any of the four boards to connect to even try a bin file.

I upload to ESP32s every day without issue.

I have tried 3 different USB-C cables (all of which work with ESP32) and they do not work with your board.

I have tried every combination and sequence of power up, S1 press, S2 press, USB C connection sequence and nothing gets the boards connected.
