Pars, Thanks for the reply. yeah i think you are right in my initial searching in Digikey and mouse my go to for parts it appears those parts no longer available. what would be a good way of procuring a board / boards otherwise? I'm just getting up to speed and trying to learn the ropes. I don't really want to put a custom 1 off order with a vendor, ideally i would like to leverage some of the experiences of folks more knowledgeable than i.
