Questions
How big is the Lightwand PCB?
It measures 7.5 × 2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Lightwand use?
80 parts, built around the 74AHCT125D, AP2112K-3.3, MCP73831 and MIC5219YMM. 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 Lightwand KiCad files?
From the themagicfrog/lightwandprogress repository on GitHub, at the commit this page was made from: the board is lightwand.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Lightwand design in my own project?
Its repository states no licence, so its author keeps all rights: ask themagicfrog before reusing the design.
