The Digilent D2SB FPGA-based development
board provides a very low cost and expandable
platform on which to design and implement digital
circuits of all kinds. The D2SB features a Xilinx
Spartan 2E-200 FPGA in a PQ208 package -
enough gates and I/O’s to implement a wide
range of digital circuits. The D2SB provides an
ideal platform for developing controllers or other
general-purpose circuits with minimum effort.
When combined with our other peripheral boards,
complex systems can be readily constructed. The
D2SB is fully compatible with the free WebPack
software from Xilinx, and it ships with a power
supply and programming cable so designs can be
implemented immediately without any further
costs.
