README
README.mdCharlieplex Demo Breakout Boards
This set of breakouts can be used to demonstrate how a charlieplex functions.
The Five Toggle breakout board uses on-off-on single pole, double through toggle switches. This gives each of the five output pins possible values of HIGH, LOW, and INPUT or High Impedance.
This can then be used to demonstrate how this works with the different layouts of charlieplexed LED's.

Questions
How big is the CharlieBreakout PCB?
It measures 33 × 24.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the CharlieBreakout use?
28 parts. 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 CharlieBreakout KiCad files?
From the UserHackable/Charlieplex_Demo repository on GitHub, at the commit this page was made from: the board is KiCad/CharlieBreakout/CharlieBreakout.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the CharlieBreakout design in my own project?
Its repository states no licence, so its author keeps all rights: ask UserHackable before reusing the design.
