Questions
How big is the RF Attenuator Board PCB?
It measures 27.9 × 20.3 mm and has 4 copper layers, 1.6 mm thick.
What parts does the RF Attenuator Board use?
35 parts, built around the MIC5205YM5. 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 RF Attenuator Board KiCad files?
From the ckflight/RF_ATTENUATOR_HARDWARE repository on GitHub, at the commit this page was made from: the board is RF Attenuator Board.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the RF Attenuator Board design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
