Comparator: common questions

How big is the Comparator PCB?

The Comparator measures 60 × 106 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Comparator?

76 components, from 34 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the Comparator design files?

From the microresearch/allcolours repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the Comparator design in my own project?

The repository has no license, so all rights stay with microresearch. Use it as a reference, and ask the author before reusing the design.
