Questions

How big is the Led clock PCB?

It measures 121.3 × 139.1 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Led clock use?

328 parts, built around the ATMEGA328P-AU, FT232RL, DS3231MZ+ and MPM3620AGQV. 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 Led clock KiCad files?

From the stevenrkeyes/led_clock_hardware repository on GitHub, at the commit this page was made from: the board is led_clock.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.

Can I use the Led clock design in my own project?

Its repository states no licence, so its author keeps all rights: ask stevenrkeyes before reusing the design.
