Questions
How big is the HatBoard PCB?
It measures 86 × 54.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the HatBoard use?
50 parts, built around the SN74LVC4245APW. 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 HatBoard KiCad files?
From the synthkore/drivepackhw repository on GitHub, at the commit this page was made from: the board is HatBoard/HatBoard.kicad_pcb and its schematic BaseBoard/BaseBoard.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the HatBoard design in my own project?
Its repository states no licence, so its author keeps all rights: ask synthkore before reusing the design.
