I’ve just received a 18-Channel 8-bit PWM LED Driver w/ I2C Interface that I ordered through amazon and tried about everything I can to get it working.
I have verified that my arduino is working ok and that it can run other i2c devices, I also checked that the LEDs are working too. But I still get nothing more than 0.01/0.02 volts output.
There is power getting to the board (I can get 5 and 1.2 volts probing the chip) and there is continuity between all the output pins (and sn3218 gnd pin) and the arduino gnd. I don’t know what else I could try to get it working. The pictures show my set up.
Thanks in advance
