Questions
How big is the TKLTheSecond PCB?
It measures 360 × 140.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the TKLTheSecond use?
302 parts, built around the BAV16WS, GT-USB-7004, K0 and K1. 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 TKLTheSecond KiCad files?
From the Denrage/customkeyboard repository on GitHub, at the commit this page was made from: the board is TKLTheSecond/TKLTheSecond/TKLTheSecond.kicad_pcb and its schematic TKL/TKL/FifthRowKeys.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the TKLTheSecond design in my own project?
Its repository states no licence, so its author keeps all rights: ask Denrage before reusing the design.
