Questions
How big is the CC1125 Transceiver PCB?
It measures 67.5 × 28.8 mm and has 4 copper layers, 1.6 mm thick.
What parts does the CC1125 Transceiver use?
83 parts, built around the GALI-74+, 3610637256S, ECS-TXO-32CSMV-400-BN-TR and USB4216-03-A. 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 CC1125 Transceiver KiCad files?
From the Flynsky/subGHzTransceiver repository on GitHub, at the commit this page was made from: the board is hardware/CC1125_Transceiver/CC1125_Transceiver.kicad_pcb and its schematic hardware/CC1125_Transceiver/CC1125_Transceiver.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the CC1125 Transceiver design in my own project?
Its repository states no licence, so its author keeps all rights: ask Flynsky before reusing the design.
