I'm still waiting for a few parts to be able to complete my system ($#&@* 7809s), but I have the WD v2.01 board assembled, the display (http://www.ebay.com/itm/261802361429) connected, and the firmware configured and loaded onto the Nano. When I power up the board using a USB phone charger to the Nano, I just get garbage on the screen. It isn't completely repeatable (i.e., the garbage doesn't always look the same), but one example is attached.
I've checked the solder joints and the wiring of the display, and I don't see any obvious problems, but I guess it's possible I'm missing something. I don't have the RX or TX boards running yet, but I expected I'd at least get an intelligible display on the WD board even if there was no data. Where should I start looking?
