Questions
How big is the Whopometer PCB?
It measures 46 × 31 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Whopometer use?
49 parts, built around the W25Q128JVSIQ, AMS1117-3.3 and MPU-6050. 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 Whopometer KiCad files?
From the ibsal/Whopometer repository on GitHub, at the commit this page was made from: the board is Whopometer/Whopometer.kicad_pcb and its schematic Whopometer/Whopometer.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Whopometer design in my own project?
Its repository states no licence, so its author keeps all rights: ask ibsal before reusing the design.
