Questions
How big is the Ammeter PCB?
It measures 20.3 × 10.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Ammeter use?
16 parts. 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 Ammeter KiCad files?
From the 21km43/Ammeter repository on GitHub, at the commit this page was made from: the board is Ammeter.kicad_pcb and its schematic Ammeter.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Ammeter design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
