Questions
How big is the TinyGawant PCB?
It measures 67.3 × 27.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the TinyGawant use?
29 parts, built around the CRM2512-FX-51R0ELF, GMC21X7R103J50NT, CDBW46-G and 156125RS57000. 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 TinyGawant KiCad files?
From the N6ARA/TinyGawant repository on GitHub, at the commit this page was made from: the board is PCB/TinyGawant/TinyGawant.kicad_pcb and its schematic PCB/TinyGawant/TinyGawant.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the TinyGawant design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
