Questions
How big is the Hackboard PCB?
It measures 309.6 × 142.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Hackboard use?
170 parts. 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 Hackboard KiCad files?
From the shlinke/ShlimKEY75 repository on GitHub, at the commit this page was made from: the board is PCB/hackboard.kicad_pcb and its schematic PCB/hackboard.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Hackboard design in my own project?
Its repository states no licence, so its author keeps all rights: ask shlinke before reusing the design.
