I2C 4CH AC LED Dimmer Module
Hello,
I have problems with I2C 4CH AC LED Dimmer Module and easpberry pi4B.
I have raspbeery 4b with 5A power suply I ise gpio 3 ports relais board and a I2C 4CH AC LED Dimmer Module. But several times the 4channel led dimmer fals out and cant xontrol the lights. When i scan for i2c bus adress then nothing is found. Then a few times later it works again. And goes so on and on.
Hmm, I am afraid that when i2cdetect does not see the device, it looks a hardware issue.
What you could try, if possible, to replace the wires between the PI and the dimmer device. Also reconnecting the wires again on the pins, could help.
Other than that I do not have any ideas. Maybe buy a second one as backup or for testing.
