PortaPack H1 is portability add-on hardware for the HackRF One software-defined radio (SDR). Schematic ========= The schematic was drawn using KiCad 4.0.6. Schematic symbols are cached in the design files, but are also available in a separate repository: https://github.com/sharebrained/library-kicad/ PCB === The circuit board was designed using KiCad. PCB footprints are cached in the design files, but are also avaliable in a separate repository: https://github.com/sharebrained/library-kicad/ The PCB is a four-layer design. Services such as OSHPark.com have suitable four-layer stack ups. CPLD ==== The CPLD bitstream is prepared using Altera Quartus tools. The CPLD is programmed from within the PortaPack firmware, by bit-banging the JTAG pins from the HackRF One's microcontroller.
