Questions
How big is the Piscsi PCB?
It measures 65 × 56 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Piscsi use?
97 parts, built around the SN74LS641-1DW and SM4007PL. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Piscsi KiCad files?
From the PiSCSI/piscsi-hw repository on GitHub, at the commit this page was made from: the board is piscsi_2p6/piscsi.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Piscsi design in my own project?
Its repository states no licence, so its author keeps all rights: ask PiSCSI before reusing the design.
