Questions

How big is the PlayDice PCB?

It measures 40 × 110 mm and has 2 copper layers, 1.6 mm thick.

What parts does the PlayDice use?

31 parts, built around the TL072, LM1117-5.0, MMBT3904 and B10K. 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 PlayDice KiCad files?

From the dchwebb/PlayDice repository on GitHub, at the commit this page was made from: the board is Hardware/PlayDice.kicad_pcb and its schematic Hardware/PlayDice.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the PlayDice design in my own project?

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