pi.keeb
meet pi.keeb my first hardware project, all thanks to the nice peeps at the Hack CLub, this macro pad acts as multi action keypad, can launch apps, turn up and down the volume and all other normal macro pad stuff. Heavily inspired by the Treasure type 9 design, with a touch of functionality!

Bibliography
This project would not have been possible without the help of the amazing people of the internet, the blueprint guide and a bit of AI
I used ai to find out more about the Controller learn about key matrix, how to code QMK for my keyboard and some basic information (i wanted to be completely transparent about the use of ai in this project)

Questions
How big is the Pi.keeb PCB?
It measures 66.7 × 66.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Pi.keeb 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 Pi.keeb KiCad files?
From the piVerified/pi.gridboard repository on GitHub, at the commit this page was made from: the board is PCB/pi.keeb.kicad_pcb and its schematic PCB/pi.keeb.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Pi.keeb design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
