Questions
How big is the Widget PCB?
It measures 61 × 30 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Widget use?
83 parts, built around the CM1293A-04SO(ES). 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 Widget KiCad files?
From the melair/ktane repository on GitHub, at the commit this page was made from: the board is PCB/Edgework/Widget/Widget.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Widget design in my own project?
Its repository states no licence, so its author keeps all rights: ask melair before reusing the design.
