Questions
How big is the ESC v1 PCB?
It measures 49.5 × 49.5 mm and has 4 copper layers, 1.6 mm thick.
What parts does the ESC v1 use?
123 parts, built around the ADUM1201AR 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 ESC v1 KiCad files?
From the 22060/2025 repository on GitHub, at the commit this page was made from: the board is kicad/ESC_v1/ESC_v1.kicad_pcb and its schematic kicad/EDzissen/EDzissen.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the ESC v1 design in my own project?
Its repository states no licence, so its author keeps all rights: ask 22060 before reusing the design.
