Questions

How big is the Current limiter PCB?

It measures 59.5 × 26 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Current limiter use?

8 parts, built around the IRF9Z34N. 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 Current limiter KiCad files?

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

Can I use the Current limiter design in my own project?

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