The PS32 boards will be available to the tech guys. The upgrade kits can be purchased by everyone. Matt, the boards you want are available now. Total plug and play. Pull the 4 pin, 5 pin, 7 pin, 8 pin, and 12 pin off your blown 5 volt board and plug them into the replacement board. Good to go. You do not have to do anything with the Mux. Just plug in the board. All existing wire stays in place.
