Questions
How big is the Variable motor driver PCB?
It measures 45 × 45 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Variable motor driver use?
23 parts, built around the 74HC595 and 1N4148W. 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 Variable motor driver KiCad files?
From the adeboni/math-camp-synth repository on GitHub, at the commit this page was made from: the board is 2023-Jukebox/hardware/variable_motor_driver/variable_motor_driver.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Variable motor driver design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
