Questions
How big is the Modern keyboard template PCB?
It measures 44 × 44.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Modern keyboard template use?
193 parts, built around the STM32F072CBT6, PRTR5V0U2X and TXB0101DBV. 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 Modern keyboard template KiCad files?
From the CalebJM04/Keyboard-PCB repository on GitHub, at the commit this page was made from: the board is modern-keyboard-template/modern-keyboard-template.kicad_pcb and its schematic modern-keyboard-template/marbastlib-main/libmanagement/libmanagement.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Modern keyboard template design in my own project?
Its repository states no licence, so its author keeps all rights: ask CalebJM04 before reusing the design.
