Questions
How big is the Talkclock PCB?
It measures 50 × 50 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Talkclock use?
53 parts, built around the PAM8301AAF, BLM18PG221SN1 and ST-USB-001G. 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 Talkclock KiCad files?
From the dholth/mesh repository on GitHub, at the commit this page was made from: the board is talkclock/talkclock.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Talkclock design in my own project?
Its repository states no licence, so its author keeps all rights: ask dholth before reusing the design.
