The hardware is built around a microchip PIC18F2550, this microcontroller has on board USB capabilities. The schematic and PCB have been designed in Kicad, an open source EDA solution
The PCB files are available in Gerber format and the schematic in pdf in the download section so that you can open them with your favourite tool.
The interface to the target PIC processor uses TTL levels (0 and 5 volts) which limits the hardware to the PIC10, PIC12, PIC16, PIC17, PIC18 and dsPIC30 series of processors. The hardware (from version 0.3) is capable of creating levels for PIC24 / PIC33 / PIC18FXXJXX devices as well.
