Questions
How big is the Radio PCB?
It measures 65 × 56 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Radio use?
90 parts, built around the 24C16 and GTL2000DGG. 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 Radio KiCad files?
From the hedj/radio repository on GitHub, at the commit this page was made from: the board is hardware/radio.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Radio 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).
