Questions
How big is the Decoder PCB?
It measures 77.7 × 45.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Decoder use?
27 parts, built around the ATMEGA328P-AU, MAX481EPA+ and 74HC595. 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 Decoder KiCad files?
From the ksmonkey123/moba3 repository on GitHub, at the commit this page was made from: the board is pcbs/light_decoder/decoder.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Decoder design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
