Questions
How big is the Servo PCB?
It measures 100 × 62 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Servo use?
90 parts, built around the 74AHC1G125GW, GS8331-TR, BSS138 and MBRA140. 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 Servo KiCad files?
From the SparkyBobo/animatronics repository on GitHub, at the commit this page was made from: the board is hardware/servo/servo.kicad_pcb and its schematic hardware/diagnostics/diagnostics.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Servo 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).
