Questions
How big is the Macro4 PCB?
It measures 48 × 48 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Macro4 use?
29 parts, built around the AP2112K-3.3, WS2812B and BSS138. 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 Macro4 KiCad files?
From the joshajohnson/macro4 repository on GitHub, at the commit this page was made from: the board is hardware/0.1/macro4.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Macro4 design in my own project?
Its repository states no licence, so its author keeps all rights: ask joshajohnson before reusing the design.
