Questions
How big is the MiniWhip PCB?
It measures 40.3 × 44.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the MiniWhip use?
41 parts, built around the L7812 and BC558. 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 MiniWhip KiCad files?
From the oe2lsp/miniWhip repository on GitHub, at the commit this page was made from: the board is miniWhip.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the MiniWhip design in my own project?
Its repository publishes it under the GPL-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
