Questions
How big is the Gaba PCB?
It measures 20 × 20 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Gaba use?
28 parts, built around the TLV9001IDCK, PAM8301AAF, AO3401A and CMC-4015-40P. 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 Gaba KiCad files?
From the daimapi/soundkey repository on GitHub, at the commit this page was made from: the board is gaba/main/main.kicad_pcb and its schematic _restore_backup_2026-08-17T17-30-11-840/soundkey.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Gaba design in my own project?
Its repository states no licence, so its author keeps all rights: ask daimapi before reusing the design.
