Questions
How big is the 7seg encoder PCB?
It measures 74.9 × 44.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the 7seg encoder use?
17 parts, built around the CD74HC194E. 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 7seg encoder KiCad files?
From the mat3ck/eirbot1a_2018 repository on GitHub, at the commit this page was made from: the board is pcb/7seg/7seg_encoder/7seg_encoder.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the 7seg encoder 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).
