I had acquired aboard through the generosity of our own Buck Rogers. But I cannot seem to find any information on it. Though I did come up with a schematic from an earlier version.
Power in looks to be 9 volts, if the silk screen is not covered up by a component. That just seemed a little unusual, since there is no range of voltage input.
I am not sure if this is the actual product#, and doc title: 28138-PDB-v2.0.pdf
The board is labeled Professional Development Board Rev C.
Thanks for any help in advance.
