Questions
How big is the ECE299 ClockRadio PCB?
It measures 50 × 60 mm and has 2 copper layers, 1.6 mm thick.
What parts does the ECE299 ClockRadio use?
48 parts, built around the LM386 and DMG2305UX. 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 ClockRadio KiCad files?
From the tamiaselder/ECE299_ClockRadio repository on GitHub, at the commit this page was made from: the board is hardware/Main.kicad_pcb and its schematic hardware/Input.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the ECE299 ClockRadio design in my own project?
Its repository states no licence, so its author keeps all rights: ask tamiaselder before reusing the design.
