Questions
How big is the Altimeter Module PCB?
It measures 69.5 × 62.6 mm and has 4 copper layers, 1.61 mm thick.
What parts does the Altimeter Module use?
106 parts, built around the STM32F103CBT6, ISO1042BDWVR, MS560702BA03-50 and TPM8837C-SO1R. 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 Altimeter Module KiCad files?
From the Queens-Rocket-Engineering-Team/av-hardware repository on GitHub, at the commit this page was made from: the board is recovery/AltimeterModule/Altimeter_Module.kicad_pcb and its schematic libraries/prop/PT_module.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Altimeter 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.
