Hi Im looking for advise on connecting a mpg to my ucbb breakout board
in running uccnc and a uc300eth

my question is where the a anb b wires from the mpg connect to the breakout board

thanks

You can connect them to any of the inputs of the UCBB, then you just have to configure the MPG pins according to your connections.

so do i put them into the negative position on the input pin or the positive?
