Questions
How big is the Power Module PCB?
It measures 69.5 × 62.6 mm and has 4 copper layers, 1.61 mm thick.
What parts does the Power Module use?
131 parts, built around the STM32F103C8T6, ISO1042BDWVR, ACS37041KLHBLT-010B3 and AMS1117-3.3. 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 Power Module KiCad files?
From the Queens-Rocket-Engineering-Team/Avionics-23-26 repository on GitHub, at the commit this page was made from: the board is Schematics/Power_Module/Power_Module.kicad_pcb and its schematic Schematics/Altimeter_Module/Altimeter_Module.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Power Module design in my own project?
Its repository states no licence, so its author keeps all rights: ask Queens-Rocket-Engineering-Team before reusing the design.
