op2 is a totally different animal. It is a full J2534 interface, whereas the 1.x types are pretty much just ush serial ports with a few other features.
Op2 has a powerful micro that has a lot of smarts inside, and the ability to apply varying voltages to a selectionof obdii pins.
Even if you had a schematic for it, it would be of little use (other than for repairing dead parts), as all the good stuff is software.
