We are running a clearance sale on this scan tool: http://www.scantool.net/scan-tools/elmscan-pwm.html I made a post a while back, about selling the boards only (no cables, no ELM320). If enough people are interested to justify setting up a separate listing, we can sell these boards for $1 or so (or less, if you buy more than one). Circuit schematics are here: http://www.scantool.net/scantool/downloads/13/elm_pwm_11.pdf The board can be used as a general-purpose PIC development board. If you know of any school or college that could put the boards to good use, we're willing to give them away for free. Sorry, the board is not RoHS compliant (contains lead).
