Questions
How big is the Hackpad PCB?
It measures 92.3 × 64.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Hackpad use?
11 parts, built around the PCF8574AP. 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 Hackpad KiCad files?
From the 3XAY/3XAY_HackPad repository on GitHub, at the commit this page was made from: the board is KiCad/hackpad.kicad_pcb and its schematic KiCad/hackpad.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Hackpad design in my own project?
Its repository states no licence, so its author keeps all rights: ask 3XAY before reusing the design.
