Questions
How big is the Lightctrl PCB?
It measures 71.1 × 22.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Lightctrl use?
32 parts, built around the ESP-WROOM-02, BSS138 and IRF8788PBF. 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 Lightctrl KiCad files?
From the polygon/lightctrl repository on GitHub, at the commit this page was made from: the board is pcb/lightctrl.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Lightctrl design in my own project?
Its repository states no licence, so its author keeps all rights: ask polygon before reusing the design.
