Questions
How big is the TKL Keyboard PCB?
It measures 347.7 × 128.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the TKL Keyboard use?
200 parts, built around the ATMEGA32U4-AU and PRTR5V0U2X. 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 TKL Keyboard KiCad files?
From the Mcube728/TKL-Keyboard repository on GitHub, at the commit this page was made from: the board is TKL Keyboard.kicad_pcb and its schematic TKL Keyboard.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the TKL Keyboard design in my own project?
Its repository states no licence, so its author keeps all rights: ask Mcube728 before reusing the design.
