Questions
How big is the CAL4809 PCB?
It measures 36 × 36 mm and has 2 copper layers, 1 mm thick.
What parts does the CAL4809 use?
31 parts, built around the ADXL362BCCZ-RL, EVQP7A+J and BAT-HLD-001-TR. 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 CAL4809 KiCad files?
From the kentN/CAL4809 repository on GitHub, at the commit this page was made from: the board is Hardware/KiCAD/CAL4809_PCB/CAL4809.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the CAL4809 design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
