How do I identify the connector board I need?
Attached is a picture showing the different versions of the connector board for the Pro35.
A was in the original Pro35 and did not offer any voltage protection.
B was the first attempt at voltage protection
C was introduced with the MKII and had a complete voltage regulator on the board.
D is the current one as of July 2009; the voltage regulator is now on the main board.
