Questions
How big is the QuasarSDR PCB?
It measures 71 × 126 mm and has 6 copper layers, 1.56 mm thick.
What parts does the QuasarSDR use?
454 parts, built around the AD9361BBC, TPS7A8101DRB, LP5907MFX-3.3 and 74AUP1G08GS. 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 QuasarSDR KiCad files?
From the petrinm/QuasarSDR-Hardware repository on GitHub, at the commit this page was made from: the board is sdr/QuasarSDR.kicad_pcb and its schematic backplane/QuasarBackplane.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the QuasarSDR design in my own project?
Its repository publishes it under the CERN-OHL-W-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
