Questions
How big is the ESC v2 PCB?
It measures 50 × 50 mm and has 4 copper layers, 1.6 mm thick.
What parts does the ESC v2 use?
144 parts, built around the AMS1117-3.3, AMS1117-5.0, RH6L040BGTB1 and 1N5819WS. 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 v2 KiCad files?
From the 22060/2026 repository on GitHub, at the commit this page was made from: the board is kicad/ESC_v2/ESC_v2.kicad_pcb and its schematic kicad/ESC_v2/ESC_v2.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the ESC v2 design in my own project?
Its repository states no licence, so its author keeps all rights: ask 22060 before reusing the design.
