Questions

How big is the MmWave radarBoard PCB?

It measures 55 × 84.1 mm and has 6 copper layers, 1 mm thick.

What parts does the MmWave radarBoard use?

275 parts, built around the MX25R1635FZUIH0, PMEG3020ER, BSS123 and NUP2105L. 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 MmWave radarBoard KiCad files?

From the EmielV2002/mmWave-radarBoard repository on GitHub, at the commit this page was made from: the board is mmWave-radarBoard/mmWave-radarBoard.kicad_pcb and its schematic mmWave-radarBoard/COM_busses.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the MmWave radarBoard 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).
