Boards are slated to arrive on Saturday, 1.17, and with a holiday weekend, I imagine I will be able to find out if my design at least communicates with the programmer. I have the Master/Sink board designed (it was a very small change from the Slave/Source board), but I believe it prudent to put my hands on the first board and get a feel for how it came out before I submit the next set to OshPark.
