Questions
How big is the Pulltab PCB?
It measures 22.1 × 21.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Pulltab use?
9 parts. 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 Pulltab KiCad files?
From the explosion33/ARES repository on GitHub, at the commit this page was made from: the board is Hardware/PullTab/pulltab.kicad_pcb and its schematic Hardware/Flight_Computer/ARES_FC.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Pulltab design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
