Questions
How big is the Matrix clock PCB?
It measures 200 × 80 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Matrix clock use?
528 parts, built around the TLC5940PWP. 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 Matrix clock KiCad files?
From the b00lduck/stm32f4-matrixclock repository on GitHub, at the commit this page was made from: the board is kicad/matrix-clock.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Matrix clock design in my own project?
Its repository states no licence, so its author keeps all rights: ask b00lduck before reusing the design.
