KC868-A8 - vinicius.marthes - 07-22-2024
Hello, I bought a KC868-A8, but in my excitement I ended up connecting it directly to the USB and cell phone charger. It is visible via USB but does not record anything. At startup, it does not test the relays, it just flashes the lights quickly, but the pilot light works. I've already replaced the IC CH340C, tested the components in the USB and 12v input circuits but I can't find out what else could have burned out. I would be grateful if someone could help me. Thanks.

you need download KCS firmware firstly. KCS v2 firmware online guide: https://www.kincony.com/esp32-kcsv2-firmware.html
install USB driver for Windows OS firstly. USB driver download link: https://www.kincony.com/download/CH341SER.zip

Thanks for answering. I downloaded the ch340c driver, ok. I downloaded the flash and firmware KCS_KC868_A8_V2.1.1, ran it but it didn't work. I think I burned the sign. I do not know what else to do.

if COM port number is correct, you can try to use another USB-C cable.

Maybe when connecting it directly to the cell phone charger via USB-C, I damaged another component, which I couldn't identify.

not sure, maybe.
