Questions
How big is the Allcolours PCB?
It measures 101.3 × 106.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Allcolours use?
246 parts, built around the TL082, MCP6002-I/P, MAX4392ESA+ and L78M10AGT. 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 Allcolours KiCad files?
From the microresearch/allcolours repository on GitHub, at the commit this page was made from: the board is all_colours_kicad/allcolours.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Allcolours design in my own project?
Its repository states no licence, so its author keeps all rights: ask microresearch before reusing the design.
