Jim,

We won't know the actual cost-per-board until the board CAD design is finished, and a complete BOM is made. I'll be making these in multiple-up panels so they break apart like crackers, so it's cheaper per board, but finished/assembled board prices won't be known until the design is completed.

If you get free engineering samples, just send them to me directly. We'll deduct the cost per controller from what you'll need to pay when the PCB design is ready, and we make the group buy.

Note: Anyone else that may be interested in this project, please submit questions, recommendations, etc to this thread; http://www.picbasic.co.uk/forum/showthread.php?t=13240

It's been moved to the off-topic area for a reason..
