Questions
How big is the Motorized Fader Driver PCB?
It measures 135 × 35 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Motorized Fader Driver use?
55 parts, built around the RP2040, DRV8833PWP, W25Q128JVSIQ and ABM8-272-T3. 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 Motorized Fader Driver KiCad files?
From the ApolloFops/Motorized-Fader-Driver repository on GitHub, at the commit this page was made from: the board is Motorized Fader Driver.kicad_pcb and its schematic Motorized Fader Driver.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Motorized Fader Driver design in my own project?
Its repository states no licence, so its author keeps all rights: ask ApolloFops before reusing the design.
