Questions
How big is the GR ATTiny LED PCB?
It measures 58 × 42 mm and has 2 copper layers, 1.6 mm thick.
What parts does the GR ATTiny LED use?
55 parts, built around the ATTINY804-SSN, BSS138 and SK6812MINI-E. 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 GR ATTiny LED KiCad files?
From the GadgetReboot/8ChLED repository on GitHub, at the commit this page was made from: the board is KiCad/GR_ATTiny_LED.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the GR ATTiny LED design in my own project?
Its repository states no licence, so its author keeps all rights: ask GadgetReboot before reusing the design.
