Questions
How big is the Radar synth PCB?
It measures 50 × 56 mm and has 4 copper layers, 1.53 mm thick.
What parts does the Radar synth use?
87 parts, built around the 74AUP1G34GW, PL133-27GC-R, SN74AUP1G04DCKR-TP and LMX2572RHAT. 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 Radar synth KiCad files?
From the sigma0us/radar-synth repository on GitHub, at the commit this page was made from: the board is hardware/radar-synth.kicad_pcb and its schematic hardware/lmx2572_rf_pll.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Radar synth design in my own project?
Its repository states no licence, so its author keeps all rights: ask sigma0us before reusing the design.
