serial port issue
#1
Dear Kincony,

I've recently received my KC868-A8S board from your store on Aliexpress.
However it seems like my new board is not functioning.

I've connected it to 12V power.
Then connected to USB-C cable from board to my laptop.
Nothing is showing up in new serial ports.
I've tested different cables, different usb ports and two different laptops.
My other esp32 board with ttl to serial converter ch340 work just fine.
Only my new kc868-a8s board does not want to work.

Kindly let me know what to do next.

Thank you.

Yes, my board is connected to 12v DC power source. When connected I can hear each relay clicking. But no serial port discovered on any laptops.
