README
README.mdKyle's GREEN Macropad
It's special because it's green nothing else. this is my first macropad or engineering project in general so its not perfect, but I did spend a lot of time figuring everything out especially since I wanted it to be 3 x 3 not just 3 keys.
Challenges
literally everything I had to restart because I didn't know you had to space the keys 19.05mm and ended messing everything up because I couldn't figure out why it didn't align with the case I also found the fusion interface super confusing, my mouse wheel broke halfway so zooming in and out was a pain

Questions
How big is the Hackpadv2 PCB?
It measures 66.7 × 90.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Hackpadv2 use?
19 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 Hackpadv2 KiCad files?
From the mateo-cpu3/Greenpad repository on GitHub, at the commit this page was made from: the board is Pcb/hackpadv2.kicad_pcb and its schematic Pcb/hackpadv2.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Hackpadv2 design in my own project?
Its repository states no licence, so its author keeps all rights: ask mateo-cpu3 before reusing the design.
