KC868-A8 PCF8574 Communication - msinfo - 06-01-2024
Hello, i've been using the KC868-a8 for a long time and one day it stopped working. I'm using it with esphome and i don't seem to have communication with the pcf8574 output. The i2c bus isn't find it.
ps: I tried to resolder the output pcf8574 didn't work.

you can replace a new power supply. if power supply is ok, maybe need replace a PCF8574 chip.

Do you mean to replace the 12v power supply with another ? I have 2 boards connected with the same power supply and 1 of them works.

ok, if this case, you can try to replace a new PCF8574 chip.
