Questions
How big is the DifferentialEncoderSlave PCB?
It measures 49.5 × 35.2 mm and has 4 copper layers, 1.6 mm thick.
What parts does the DifferentialEncoderSlave use?
21 parts, built around the SN75C1167N and LDFM33PVR. 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 DifferentialEncoderSlave KiCad files?
From the Wetmelon/DifferentialSPIEncoder repository on GitHub, at the commit this page was made from: the board is Slave/DifferentialEncoderSlave.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the DifferentialEncoderSlave 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).
