Questions
How big is the STM32 and GPS Technology PCB PCB?
It measures 68 × 53.1 mm and has 4 copper layers, 1.6 mm thick.
What parts does the STM32 and GPS Technology PCB use?
66 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 STM32 and GPS Technology PCB KiCad files?
From the JayTzw/Mechanical---Robotics---Electronics repository on GitHub, at the commit this page was made from: the board is E-CAD/KiCAD/KiCad Projects/STM32 and GPS Technology PCB/STM32 and GPS Technology PCB.kicad_pcb and its schematic E-CAD/KiCAD/KiCad Projects/Enhanced Arduino MEGA 2560 Rev 3 PCB/Enhanced Arduino MEGA 2560 Rev 3 PCB.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the STM32 and GPS Technology PCB design in my own project?
Its repository states no licence, so its author keeps all rights: ask JayTzw before reusing the design.
