Questions
How big is the Pov badge PCB?
It measures 54.4 × 140 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Pov badge use?
63 parts, built around the 74LVC1G17Z, ESP32-C3-MINI-1, AP2112K-3.3 and HX4054A. 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 Pov badge KiCad files?
From the bornhack/badge2024 repository on GitHub, at the commit this page was made from: the board is pov_badge.kicad_pcb and its schematic 16-ws2812.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Pov badge design in my own project?
Its repository publishes it under the CC-BY-SA-4.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
