Development Board for phyCORE-PXA255
62 
PHYTEC Meßtechnik GmbH 2004 L-657e_0
The Expansion Board is connected over two, 2.0 mm, 44-pin flat band
cables. The pinout of the Development Board plugs X30 and X31 is
given in the following table. Using a customer-specific Expansion
Board instead of the standard Expansion Board is also possible given
the removable connection via flat band cables. The connector X10
contains the signals for the CompactFlash card. The voltage pin
CF_VCC can only be used for the CF card, because it is switched on
or off depending on the operating status of the socket.
