Questions
How big is the Tinyk20 PCB?
It measures 24.8 × 64.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Tinyk20 use?
41 parts, built around the MK20DX128VFT5, 74LS126PC, LT1129CST-3.3#PBF and BAS40-05. 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 Tinyk20 KiCad files?
From the Muriukidavid/tinyk20 repository on GitHub, at the commit this page was made from: the board is tinyK20.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Tinyk20 design in my own project?
Its repository states no licence, so its author keeps all rights: ask Muriukidavid before reusing the design.
