Questions
How big is the Smd practice PCB?
It measures 99 × 99 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Smd practice use?
362 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 Smd practice KiCad files?
From the krunchiekrunch/smd-practice repository on GitHub, at the commit this page was made from: the board is pcb/smd-practice.kicad_pcb and its schematic pcb/smd-practice.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Smd practice design in my own project?
Its repository states no licence, so its author keeps all rights: ask krunchiekrunch before reusing the design.
