Questions
How big is the 87keyboard PCB?
It measures 347.7 × 123.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the 87keyboard use?
420 parts, built around the STM32F070RBT6, M24256-DFMN6TP, MCP1700T-3302E/TT(MS) and TXS0101DBV. 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 87keyboard KiCad files?
From the danielpclin/87keyboard repository on GitHub, at the commit this page was made from: the board is 87keyboard.kicad_pcb and its schematic 87keyboard.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the 87keyboard design in my own project?
Its repository states no licence, so its author keeps all rights: ask danielpclin before reusing the design.
