Questions
How big is the ECE299 PCB?
It measures 76.2 × 85.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the ECE299 use?
39 parts, built around the LM386. 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 ECE299 KiCad files?
From the WilFehr/ECE299 repository on GitHub, at the commit this page was made from: the board is PCB/PCB.kicad_pcb and its schematic PCB/PCB.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the ECE299 design in my own project?
Its repository states no licence, so its author keeps all rights: ask WilFehr before reusing the design.
