The DIO4 Digital I/O board (the DIO4) provides a simple and inexpensive ready-made source for several useful I/O devices and ports. It can be used with the D2SB or D2FT boards to provide a convenient source of I/O devices that are useful in the design and debug of digital circuits. All I/O devices are directly mapped to I/O pins on the system FPGA, so it is very quick and easy to use.
