Questions
What parts does the ControlBoard use?
106 parts, built around the MCP2551-I/P, PCF8574T, UDN2981A-T and LM317. 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 ControlBoard KiCad files?
From the knoerk/MicroGasExchange repository on GitHub, at the commit this page was made from: the board is KiCAD/Controlboard/ControlBoard.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the ControlBoard design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
