Questions
How big is the Busterm PCB?
It measures 42.5 × 64.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Busterm use?
38 parts, built around the BC327, BC547, BD137 and BD138. 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 Busterm KiCad files?
From the felge1966/APC40 repository on GitHub, at the commit this page was made from: the board is Busterm/Busterm.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Busterm design in my own project?
Its repository publishes it under the Unlicense licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
