Questions
How big is the Accelerometer PCB PCB?
It measures 77 × 55 mm and has 2 copper layers, 1.63 mm thick.
What parts does the Accelerometer PCB use?
21 parts, built around the TPSM84205EAB and M20-8770442. 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 Accelerometer PCB KiCad files?
From the JamesRop/VIMS-Accelerometer-PCB repository on GitHub, at the commit this page was made from: the board is Accelerometer PCB.kicad_pcb and its schematic Accelerometer PCB (No Volt Reg).kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Accelerometer PCB design in my own project?
Its repository states no licence, so its author keeps all rights: ask JamesRop before reusing the design.
