Questions
How big is the EV12Controller PCB?
It measures 84 × 64 mm and has 2 copper layers, 1.6 mm thick.
What parts does the EV12Controller use?
70 parts, built around the ESP32-WROOM-32, SN74LV1T34DBV, SS8050 and WS2812B. 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 EV12Controller KiCad files?
From the S-A-M-J/12EV repository on GitHub, at the commit this page was made from: the board is pcb/EV12Controller/EV12Controller/EV12Controller.kicad_pcb and its schematic pcb/EV12Controller/EV12Controller/EV12Controller.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the EV12Controller design in my own project?
Its repository states no licence, so its author keeps all rights: ask S-A-M-J before reusing the design.
