Here is the ELM322 board that I built based on their schematic and PCB.

Two things to note:

First is that I used a DB9 instead of the DB25. (personal choice)
Second I built a DB9-->Clips adapter for testing. You may want to do the same. (all Radio Shack parts)

If you want to use it for automotive diagnostics you will need to order the cable from scantool.net when you order the chip.
