Questions
How big is the Controller PCB?
It measures 104 × 241 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Controller use?
78 parts, built around the MAX485ED, DRV8837DSG, L7805 and 1N5819W. 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 Controller KiCad files?
From the gmartens/DMX-Controller repository on GitHub, at the commit this page was made from: the board is design/controller.kicad_pcb and its schematic design/buttons.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Controller design in my own project?
Its repository states no licence, so its author keeps all rights: ask gmartens before reusing the design.
