Questions
How big is the Sistdig PCB?
It measures 101.6 × 107.9 mm and has 2 copper layers, 1.58 mm thick.
What parts does the Sistdig use?
21 parts, built around the LM358, L293D, CNY70 and 74HC14. 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 Sistdig KiCad files?
From the dinge321/motor_pcb repository on GitHub, at the commit this page was made from: the board is sistdig.kicad_pcb and its schematic sistdig.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Sistdig design in my own project?
Its repository states no licence, so its author keeps all rights: ask dinge321 before reusing the design.
