Preonic Rev 3 Schematics

[agoldstein03]

Seems like this repo may be inactive, but just in case, figured I'd ask here. I got a used Preonic keyboard which was working great for maybe an hour, then suddenly stopped working. I identified two components which get very hot, and I'd like to try to go further in figuring out how to potentially repair this, so a schematic would be very helpful. Thanks!
