Questions
How big is the Controller PCB?
It measures 140 × 81 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Controller use?
54 parts, built around the ATMEGA328-PU, AMS1117-3.3 and AMS1117-5.0. 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 le-flav-b/VEMAR repository on GitHub, at the commit this page was made from: the board is hardware/boards/controller/controller.kicad_pcb and its schematic hardware/boards/controller/controller.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 le-flav-b before reusing the design.
