Questions
How big is the Digit Colon PCB?
It measures 140.5 × 213 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Digit Colon use?
116 parts, built around the TLC5952DAP. 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 Digit Colon KiCad files?
From the kuellenberg/7-Segment-RGB-Clock repository on GitHub, at the commit this page was made from: the board is Digit_Colon/Digit_Colon.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Digit Colon design in my own project?
Its repository states no licence, so its author keeps all rights: ask kuellenberg before reusing the design.
