Manufacturing
Obtain the three files in hardware/jlcpcb/production_files
- Upload the gerber to the order page, choose SMT assembly
- Upload the BOM and CPL file in the SMT assembly page.
Firmware
- If the flash is empty, press the BOOT0 button, then the NRST button and release both, if the firmware is already flashed, you can skip this step.
- Run
dfu-util -a 0 -s 0x08000000:leave -D si5351_gpsdo.bin
Building
Within the firmware folder, run
cmake -DCMAKE_TOOLCHAIN_FILE=cubeide-gcc.cmake -S ./ -B Release -G"Unix Makefiles" -DCMAKE_BUILD_TYPE=Release
make -C Release VERBOSE=1 -jConfiguration
The configuration can be done through the web using https://rhgndf.github.io/mini_gpsdo/

Questions
How big is the Usb si5351 gpsdo PCB?
It measures 45 × 42.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Usb si5351 gpsdo use?
74 parts, built around the ATGM336H-6N-74, MD57E33QA3, SI5351A-B-GT and H5VU10U. 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 Usb si5351 gpsdo KiCad files?
From the rhgndf/mini_gpsdo repository on GitHub, at the commit this page was made from: the board is hardware/usb_si5351_gpsdo.kicad_pcb and its schematic hardware/usb_si5351_gpsdo.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Usb si5351 gpsdo design in my own project?
Its repository states no licence, so its author keeps all rights: ask rhgndf before reusing the design.
