GoodFET20
The GoodFET20 is the third hardware revision of the GoodFET. The same board is also the basis of the BadFET20, which runs at 16MHz and optionally glitches the voltage of target chips to bypass securiy features.
CAD Files
Eagle CAD 5.x files for the design can be found in /branches/goodfet20 of the subversion repository, or as goodfet20.zip.
