Questions
How big is the Neopixelcontroller PCB?
It measures 83 × 42 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Neopixelcontroller use?
15 parts, built around the 74HCT125PW and AP2112K-3.3. 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 Neopixelcontroller KiCad files?
From the chickadee-tech/neopixelcontroller repository on GitHub, at the commit this page was made from: the board is NeopixelController.kicad_pcb and its schematic NeopixelController.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Neopixelcontroller design in my own project?
Its repository states no licence, so its author keeps all rights: ask chickadee-tech before reusing the design.
