Questions

How big is the Project4 buck converyter PCB?

It measures 44 × 41 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Project4 buck converyter use?

8 parts, built around the IRLZ44N. 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 Project4 buck converyter KiCad files?

From the nilabjo08/PCB_Designing- repository on GitHub, at the commit this page was made from: the board is project4_buck converyter.kicad_pcb and its schematic project4_buck converyter.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Project4 buck converyter design in my own project?

Its repository states no licence, so its author keeps all rights: ask nilabjo08 before reusing the design.
