Questions

How big is the LDRUNIT PCB?

It measures 25 × 34 mm and has 2 copper layers, 1.6 mm thick.

What parts does the LDRUNIT use?

27 parts. 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 LDRUNIT KiCad files?

From the mrwillem/PCBs repository on GitHub, at the commit this page was made from: the board is LDRUNIT/LDRUNIT.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.

Can I use the LDRUNIT design in my own project?

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