Questions
How big is the DifferentialEncoder PCB?
It measures 20.3 × 14 mm and has 2 copper layers, 1.6 mm thick.
What parts does the DifferentialEncoder use?
23 parts, built around the MAX3284EAUT. 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 DifferentialEncoder KiCad files?
From the Wetmelon/Differential-Encoder-Adapter repository on GitHub, at the commit this page was made from: the board is DifferentialEncoder.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the DifferentialEncoder design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
