2: power on for your KinCony S3 board.
3: remove your finger
then board will enter bootloader, you can download now.
Thank you. I have tried this but still the same.
No LEDs are lighting up when USB-C is connected.

I have been at this for over an hour now with both boards. Neither will connect.
What do you suggest?

I don't use WhatsApp.

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.

I purchased from Kincony. Order #1841.
I ordered 2 boards.
I have tried different cables and power 12V and 24V.

Do you test them before shipping?
RE: KinCony ESP32-S3 Core Board ESPHome yaml for home assistant - admin - 02-23-2025
sure, every board will have testing. OK, if you want, we can re send 2pcs of S3 board to you.
But it's strange, usually not both boards break at the same time.
RE: KinCony ESP32-S3 Core Board ESPHome yaml for home assistant - AshS - 02-23-2025
Yes, please do that.
That is really great service from you and I appreciate it. My other Kincony boards are still excellent.
Please let me know by email when you have sent them.
Thank you.
