Questions
How big is the Colorful LED PCB?
It measures 66.5 × 60 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Colorful LED use?
37 parts, built around the ATMEGA32U4-AU. 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 Colorful LED KiCad files?
From the Gabriel8503/EE_Design repository on GitHub, at the commit this page was made from: the board is colorful_LED/design/design.kicad_pcb and its schematic Blinky_5.0/GettingToBlinky5.0.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Colorful LED 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).
