Questions
How big is the MBRadioDual2 PCB?
It measures 97 × 79.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the MBRadioDual2 use?
104 parts, built around the SI4735-D60-GU, SN74CBT3253D, 74LVC1G04Z and CM1213A-01SO. 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 MBRadioDual2 KiCad files?
From the LadyRoninEngineer/Si473x repository on GitHub, at the commit this page was made from: the board is MBRF_DUAL/MBRadioDual2.kicad_pcb and its schematic MBRF_DUAL/MBRadioDual2.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the MBRadioDual2 design in my own project?
Its repository publishes it under the Unlicense licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
