RaspberryPi Universal Expansion Board

Raspberry Pi is a widely used Arm development board and the Digilent Pmod interface is used to connect low frequency, low I/O pin count peripheral modules to host controller boards.  This expansion board is a bridge to connect all kinds of Pmods to the Raspberry Pi. The board also provided much more useful features such as ADCs, 5v I/Os and Coprocessor, see specifications section for more details.
