Questions
How big is the 96 keeb PCB?
It measures 374.7 × 127 mm and has 2 copper layers, 1.6 mm thick.
What parts does the 96 keeb use?
454 parts, built around the STM32F072CBT6, PRTR5V0U2X, TXB0101DBV and 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 96 keeb KiCad files?
From the Isio-19/keebs repository on GitHub, at the commit this page was made from: the board is 96%/96_keeb.kicad_pcb and its schematic 84%/84_keeb.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the 96 keeb design in my own project?
Its repository states no licence, so its author keeps all rights: ask Isio-19 before reusing the design.
