Propeller Professional Development Board Rev. B (PPDB)


The Propeller Professional Development Board is a collector’s item now, no longer available from Parallax. In very good condition. This was from my bench collection which I must, sadly, part with.

This is the Blue Rev. B model. I do have a few of the original Gray Rev. A model as well. Please see the description below for complete product details.
