Questions
How big is the HackPad - HighWay - HackClub PCB?
It measures 45 × 58 mm and has 2 copper layers, 1.6 mm thick.
What parts does the HackPad - HighWay - HackClub use?
6 parts, built around the SK6812MINI-E. 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 - HighWay - HackClub KiCad files?
From the AsleshSura/HackPad repository on GitHub, at the commit this page was made from: the board is PCB/HackPad - HighWay - HackClub.kicad_pcb and its schematic PCB/HackPad - HighWay - HackClub.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the HackPad - HighWay - HackClub design in my own project?
Its repository states no licence, so its author keeps all rights: ask AsleshSura before reusing the design.
