Questions
How big is the Neopixel Array PCB?
It measures 69 × 80 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Neopixel Array use?
132 parts, built around the WS2812B. 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 Neopixel Array KiCad files?
From the jjhorton/PMod repository on GitHub, at the commit this page was made from: the board is PMod_Neopixel_Array/Hardware/Neopixel_Array.kicad_pcb and its schematic PMod_7Segment/hardware/PMod_7Segement.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Neopixel Array design in my own project?
Its repository states no licence, so its author keeps all rights: ask jjhorton before reusing the design.
