I designed and built the PNP board, it has the coil IGBTs, as well as an arduino pro mini to control a secondary Stepper motor ( secondary throttle plates ) as well as interface with safety sensors like the kick stand and clutch inputs.
Unfortunately the MicroSquirt died, and I couldnt get the supplier to even try to fix it , the motorolla Micro just quit and I simply couldn't bring myself to fork over ~$300 for a new one. so the project got thrown in a drawer.
So i thought, why not just build my own with Speeduino?
So this a pin compatable, same form factor board, with Extra JST headers for the extra 2 injectors, 2 coil outs and IAC.
Just saw I spelled " SPURT" wrong on the silk screen.
