The Grits Programmable I/O board has been released as source and manufacturing files. This board is built in the PC/104 embedded computer format. Programmable inputs and outputs are accessed through one or more I/O addresses, and a switchable interrupt is provided. Full design files are provided, along with manufacturing files for the board. The schematic and printed wiring board CAD files are being initially released for the GNU/Linux platform and the Eagle 4.01 CAD system. As usual, the design and all of its files are released under GPL. The link is on the Grits Programmable I/O page.
