So, I ordered a set of PB16's and as many of you know, you can't just order 1 or 2.
Therefore I have extras for sale.
These are the 'g' version which I believe is the latest iteration of the board.

They are red PCBs. $5 each plus some postage depending on qty and location.

If you don't know what this is, do a search on PB16 and you will find a long thread on the subject.
