edit: just noticed you were talking about a different board. it's the same mosfet on all of them though

scroll down to the bottom. there's no 8b listed, but i am sure the transistor is the same.
stern tech support is probably best if you need an exact schematic for that board. i'm surprised there hasn't been more outcry over this. exactly what people feared with the spike system and lack of repair documentation is exactly what has happened.
Quoted from wisefwumyogwave:Thanks for that would you mind posting what type of surface mount LEDs they use as well?
i can't tell from the schematic and can't really get a good idea of the package size from the picture above. the package size is really the important part. most white LEDs will have comparable forward voltages and operating currents.
probably worth asking stern about those. who knows if you'll get an answer, but they really should be providing this information.
