Questions
How big is the Openxcvr PCB?
It measures 101.6 × 137.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Openxcvr use?
155 parts, built around the LM4562NA, LM386, PCM1802DB and SN74CBT3253D. 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 Openxcvr KiCad files?
From the dawsonjon/OpenXcvr repository on GitHub, at the commit this page was made from: the board is pcb/openxcvr/openxcvr.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Openxcvr 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).
