Questions
How big is the CB Retrofit PCB?
It measures 180 × 56 mm and has 2 copper layers, 1.6 mm thick.
What parts does the CB Retrofit use?
24 parts, built around the LM386 and TDA1543. 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 CB Retrofit KiCad files?
From the lacyrhoades/KiCad repository on GitHub, at the commit this page was made from: the board is CB-Retrofit/CB.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the CB Retrofit 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).
