Questions
How big is the MotorFaderBoard PCB?
It measures 42 × 100 mm and has 2 copper layers, 1.6 mm thick.
What parts does the MotorFaderBoard use?
17 parts, built around the L293DD. 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 MotorFaderBoard KiCad files?
From the 8-Lambda-8/ShowControllPCBs repository on GitHub, at the commit this page was made from: the board is motorFaderBoard/motorFaderBoard.kicad_pcb and its schematic CAT_XLR/CAT_XLR.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the MotorFaderBoard 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).
