Questions
How big is the FMSMD-2 PCB?
It measures 20 × 50 mm and has 2 copper layers, 1.6 mm thick.
What parts does the FMSMD-2 use?
96 parts, built around the HR8833MTER, AO3422 and AON6504. 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 FMSMD-2 KiCad files?
From the apachecn/fm01 repository on GitHub, at the commit this page was made from: the board is doc/kicad/fmsmd-2/FMSMD-2/FMSMD-2.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the FMSMD-2 design in my own project?
Its repository states no licence, so its author keeps all rights: ask apachecn before reusing the design.
