Questions

How big is the ESC Electronics PCB?

It measures 149.5 × 74.5 mm and has 2 copper layers, 1.6 mm thick.

What parts does the ESC Electronics use?

60 parts, built around the TL051CP, UA79M08CKC and RB751V-40. 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 Electronics KiCad files?

From the bungernut/ESC_Electronics repository on GitHub, at the commit this page was made from: the board is KiCAD/ESC_Electronics/ESC_Electronics.kicad_pcb and its schematic KiCAD/ESC_Electronics/ESC_Electronics.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the ESC Electronics design in my own project?

Its repository states no licence, so its author keeps all rights: ask bungernut before reusing the design.
