Questions
How big is the Easy CW Decoder PCB?
It measures 87 × 50 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Easy CW Decoder use?
28 parts, built around the L78L05CZ. 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 Easy CW Decoder KiCad files?
From the mcquiggi/CW-Decoder repository on GitHub, at the commit this page was made from: the board is Easy CW Decoder.kicad_pcb and its schematic Easy CW Decoder.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Easy CW Decoder design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
