Questions
How big is the Rx8901ce PCB?
It measures 20.3 × 15.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Rx8901ce use?
7 parts. 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 Rx8901ce KiCad files?
From the treideme/rx8901 repository on GitHub, at the commit this page was made from: the board is pcb/rx8901ce/rx8901ce.kicad_pcb and its schematic pcb/rx8901ce/rx8901ce.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Rx8901ce 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).
