Questions
How big is the STM32 GPS Tracking Module PCB?
It measures 42.5 × 58.5 mm and has 4 copper layers, 1.6 mm thick.
What parts does the STM32 GPS Tracking Module use?
61 parts, built around the SIM808, TPS5430DDA, SMF05CT1G and U.FL-R-SMT-1. 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 GPS Tracking Module KiCad files?
From the tejashviraj19/PCB-Design-Lab repository on GitHub, at the commit this page was made from: the board is STM32 GPS Tracking Module/KiCad/STM32 GPS Tracking Module.kicad_pcb and its schematic ATtiny85-Smart-Diya/KiCad_Files/ATtiya85-smart-diya.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the STM32 GPS Tracking Module design in my own project?
Its repository states no licence, so its author keeps all rights: ask tejashviraj19 before reusing the design.
