Questions
How big is the Esc v2 PCB?
It measures 40 × 25 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Esc v2 use?
39 parts, built around the ATMEGA328PB-MU, ACT4088US-T and FAN7888M. 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 savob/esc repository on GitHub, at the commit this page was made from: the board is hardware/esc_v2/esc_v2.kicad_pcb and its schematic hardware/driver_ic_adapter/driver_ic_adapter.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 publishes it under the CERN-OHL-W-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
