Questions
How big is the DC servo PCB?
It measures 35.1 × 30.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the DC servo use?
36 parts, built around the NCS20071XV53, ZXBM5409Q-N-U and VS-10MQ100HM3/5AT. 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 DC servo KiCad files?
From the EBOThor/DTS_Board repository on GitHub, at the commit this page was made from: the board is HW/DC_servo/DC_servo/DC_servo.kicad_pcb and its schematic HW/CC_Debug/CC_Debug/CC USB hub.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the DC 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).
