Questions
How big is the Taptap PCB?
It measures 32.5 × 21.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Taptap use?
9 parts, built around the TIP120. 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 Taptap KiCad files?
From the dcpedit/taptap repository on GitHub, at the commit this page was made from: the board is pcb/TapTap.kicad_pcb and its schematic pcb/TapTap.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Taptap design in my own project?
Its repository publishes it under the CC-BY-4.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
