Bare boards?  Or Partially stuffed?

Well, it looks like the ELM320 is an 8-pin PIC, making the board
POSSIBLY "bendable" into a general purpose "8 pin PIC with a crystal,
voltage regulator, and rs232 interface, (plus two other pins connected
to "funky" electronics that you need not populate, and could connect
to other things.)  You might be able to get rid of them documenting
them a bit along those lines...  Potentially you don't even need to
populate the crystal - the PCB has nice holes that you could use to
connected those to something else.  But having the voltage regulator
and rs232 interface is sorta handy...
