View Full Version : Propeller Demo Board Rev C vs Rev D

10-07-2006, 02:56 PM
Is there any difference between Rev C and Rev D demo boards beyond the changes in nomenclature, PS /2 corrections, labels and symbols and the addition of the 1 nF cap in the electret mic circuit? I am using the demo board to drive PRC and several other boards, and am trying to make sure I don't need to upgrade to the Rev D board.

It is a much improved schematic, but I want to make sure I haven't missed anything...

Thanks, Bill

I believe with the exception of Rev A, all propeller demo board revisions are identical in functionality and peripheral pin assignments.

Only other difference between Rev.C & D is an extra pin to 5V in the VGA connector (Pin 10 I think).
