Questions
How big is the Comparator PCB?
It measures 60 × 106 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Comparator use?
105 parts, built around the ADG413BNZ and LM1117-5.0. 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 Comparator KiCad files?
From the microresearch/allcolours repository on GitHub, at the commit this page was made from: the board is comparator_v2/comparator.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Comparator design in my own project?
Its repository states no licence, so its author keeps all rights: ask microresearch before reusing the design.
