Questions
How big is the EncoderInterface PCB?
It measures 27.9 × 20.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the EncoderInterface use?
10 parts, built around the 6N137SDM. 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 EncoderInterface KiCad files?
From the CUERT-dev/ElectricalRndD_TeamDev repository on GitHub, at the commit this page was made from: the board is EncoderInterface/EncoderInterface.kicad_pcb and its schematic CozySolder/CozySolder.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the EncoderInterface design in my own project?
Its repository states no licence, so its author keeps all rights: ask CUERT-dev before reusing the design.
