Questions
How big is the Tiny radar PCB?
It measures 70 × 27.5 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Tiny radar use?
101 parts, built around the STM32L432KCU6, AD8330ACP, LMX358IQ2T and HHM1520. 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 Tiny radar KiCad files?
From the westonb/tiny-radar repository on GitHub, at the commit this page was made from: the board is pcb/tiny-radar.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Tiny radar design in my own project?
Its repository states no licence, so its author keeps all rights: ask westonb before reusing the design.
