Questions
How big is the Magnetometer Controller PCB?
It measures 120 × 100 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Magnetometer Controller use?
86 parts, built around the SN75179BD, CD4052 and 74HC595. 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 Magnetometer Controller KiCad files?
From the mjmorano/Magnetometer-System repository on GitHub, at the commit this page was made from: the board is KiCad/Controller/Magnetometer Controller.kicad_pcb and its schematic KiCad/Controller/Bypass.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Magnetometer Controller design in my own project?
Its repository states no licence, so its author keeps all rights: ask mjmorano before reusing the design.
