Questions
How big is the Brew keeb v2 PCB?
It measures 340.5 × 144 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Brew keeb v2 use?
222 parts, built around the SL2.1A and SK6812. 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 Brew keeb v2 KiCad files?
From the geg-tech/brew-keeb repository on GitHub, at the commit this page was made from: the board is PCB/brew-keeb-v2.kicad_pcb and its schematic PCB/brew-keeb-v2.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Brew keeb v2 design in my own project?
Its repository states no licence, so its author keeps all rights: ask geg-tech before reusing the design.
