Good day, I’m hoping you can help me out.
I am using your PCA9547 8-Channel I2C-Bus Multiplexer with Reset with I2C Interface device and I have my sensors connected. I am using an Arduino Uno connected to the multiplexer to power it, however, the sensors don’t seem to receive any power. Do I need to use an external 12V power supply or is this a software issue where I need to activate the sensors? My sensors do not receive any power, the light does not power on.
