Questions
How big is the LedClock PCB?
It measures 176.4 × 21.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the LedClock use?
47 parts, built around the ATMEGA32-16AU and IRL 81A. 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 LedClock KiCad files?
From the qb-creates/pov-led-clock repository on GitHub, at the commit this page was made from: the board is eda/pov-clock-kicad/LedClock.kicad_pcb and its schematic eda/esc-driver-kicad/ESCDriver.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the LedClock 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).
