Questions
How big is the STM32-GPSDO PCB PCB?
It measures 166.6 × 109.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the STM32-GPSDO PCB use?
65 parts, built around the SPX1117M3-L-5-0/TR, 74HC14 and MH2029-300Y. 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 STM32-GPSDO PCB KiCad files?
From the caiser01/BlackPill-GPSDO repository on GitHub, at the commit this page was made from: the board is PCB/STM32-GPSDO_PCB.kicad_pcb and its schematic PCB/STM32-GPSDO_PCB.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the STM32-GPSDO PCB design in my own project?
Its repository states no licence, so its author keeps all rights: ask caiser01 before reusing the design.
