Questions
How big is the Switcher PCB?
It measures 50 × 50 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Switcher use?
64 parts, built around the ESP-12E and BC817. 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 Switcher KiCad files?
From the dexterlb/led_controller repository on GitHub, at the commit this page was made from: the board is boards/bundled_esp/switcher/switcher.kicad_pcb and its schematic boards/bundled_esp/encoder/encoder.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Switcher design in my own project?
Its repository states no licence, so its author keeps all rights: ask dexterlb before reusing the design.
