Questions
How big is the LO PCB PCB?
It measures 50 × 44 mm and has 4 copper layers, 1.61 mm thick.
What parts does the LO PCB use?
99 parts, built around the LMX2592RHAR, TPS7A9101DSKT, GRT188R61C106KE13D and RC0402JR-070RL. 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 LO PCB KiCad files?
From the MortenSorensenNOR/Long-Distance-Radio repository on GitHub, at the commit this page was made from: the board is LO_PCB/LO_PCB.kicad_pcb and its schematic CLK_BOARD/CLK_BOARD.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the LO PCB design in my own project?
Its repository states no licence, so its author keeps all rights: ask MortenSorensenNOR before reusing the design.
