Questions
How big is the MagLev PCB?
It measures 120 × 120 mm and has 2 copper layers, 1.69 mm thick.
What parts does the MagLev use?
211 parts, built around the ATMEGA328P-AU, LM324, FT232RL and MCP1402. 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 MagLev KiCad files?
From the KDueck/MagLev repository on GitHub, at the commit this page was made from: the board is KiCad/MagLev/MagLev.kicad_pcb and its schematic KiCad/MagLev/MCU.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the MagLev design in my own project?
Its repository states no licence, so its author keeps all rights: ask KDueck before reusing the design.
