Questions
How big is the Hackpadmaxxing PCB?
It measures 70 × 90 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Hackpadmaxxing use?
33 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 Hackpadmaxxing KiCad files?
From the Smartlinuxcoder/hackpadmaxxing repository on GitHub, at the commit this page was made from: the board is pcb/hackpadmaxxing.kicad_pcb and its schematic pcb/hackpadmaxxing.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Hackpadmaxxing design in my own project?
Its repository states no licence, so its author keeps all rights: ask Smartlinuxcoder before reusing the design.
