Questions
How big is the PacketRadio PCB?
It measures 58 × 32 mm and has 2 copper layers, 1.6 mm thick.
What parts does the PacketRadio use?
72 parts, built around the FT232RL, PCM2912APJT, BC847 and BC857. 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 PacketRadio KiCad files?
From the elnappo/PCB repository on GitHub, at the commit this page was made from: the board is PacketRadio/PacketRadio.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the PacketRadio 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).
