Questions

How big is the Nrf5340 module PCB?

It measures 18.5 × 32.5 mm and has 4 copper layers, 1.6 mm thick.

What parts does the Nrf5340 module use?

55 parts, built around the NRF5340-DK, AP2112K-3.3 and MBR120. 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 Nrf5340 module KiCad files?

From the crohloff/nrf5340_module repository on GitHub, at the commit this page was made from: the board is nrf5340_module.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.

Can I use the Nrf5340 module design in my own project?

Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
