Questions
How big is the Booster link PCB?
It measures 50 × 50 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Booster link use?
33 parts, built around the TLC555CP and BC337. 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 Booster link KiCad files?
From the GBert/misc repository on GitHub, at the commit this page was made from: the board is booster-link/booster-link.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Booster link design in my own project?
Its repository states no licence, so its author keeps all rights: ask GBert before reusing the design.
