Questions
How big is the FrontendPCBCoupon PCB?
It measures 140 × 116 mm and has 4 copper layers, 1.61 mm thick.
What parts does the FrontendPCBCoupon use?
34 parts, built around the BWSMA-KE-P001. 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 FrontendPCBCoupon KiCad files?
From the olddudealex/funrad repository on GitHub, at the commit this page was made from: the board is Frontend/kicad/FrontendPCBCoupon/FrontendPCBCoupon.kicad_pcb and its schematic Antenna/kicad/line_array/line_array.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the FrontendPCBCoupon design in my own project?
Its repository publishes it under the CERN-OHL-P-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).
