Questions
How big is the Crowbar PCB?
It measures 50 × 32.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Crowbar use?
22 parts, built around the TYN1225. 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 Crowbar KiCad files?
From the bullestock/ledcube repository on GitHub, at the commit this page was made from: the board is pcb/crowbar/crowbar.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Crowbar design in my own project?
Its repository states no licence, so its author keeps all rights: ask bullestock before reusing the design.
