Questions
How big is the Magnetometer PCB?
It measures 60 × 39 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Magnetometer use?
36 parts, built around the ATTINY25-20PU, AD8629M/TR, SN75179BD and L78L05CZ. 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 KiCad files?
From the mjmorano/Magnetometer-System repository on GitHub, at the commit this page was made from: the board is KiCad/Magnetometer/Magnetometer.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 design in my own project?
Its repository states no licence, so its author keeps all rights: ask mjmorano before reusing the design.
