Questions

How big is the GPS Tracker STM32 PCB?

It measures 48.7 × 66.6 mm and has 2 copper layers, 1.6 mm thick.

What parts does the GPS Tracker STM32 use?

57 parts, built around the SIM808, TPS5430DDA, SMF05CT1G and AO3407A. 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 GPS Tracker STM32 KiCad files?

From the midhun09-git/KiCad-PCB-Projects repository on GitHub, at the commit this page was made from: the board is P_09) GPS Tracker with STM32/Kicad Files_9/GPS_Tracker_STM32.kicad_pcb and its schematic P_01) AC to DC Converter Circuits/Kicad Files_1/AC_DC.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the GPS Tracker STM32 design in my own project?

Its repository states no licence, so its author keeps all rights: ask midhun09-git before reusing the design.
