Questions

How big is the Isolated power PCB?

It measures 195.6 × 139.1 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Isolated power use?

269 parts, built around the SG3525A, ES2D and IRF530N-VB. 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 Isolated power KiCad files?

From the bec5-group/pid-controller repository on GitHub, at the commit this page was made from: the board is isolated-power/isolated-power.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.

Can I use the Isolated power design in my own project?

Its repository states no licence, so its author keeps all rights: ask bec5-group before reusing the design.
