Questions
How big is the Chronopy PCB?
It measures 43 × 43 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Chronopy use?
85 parts, built around the BMD-340-A-R, APDS-9960, BME680 and W25Q32JVZPIQ. 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 Chronopy KiCad files?
From the ChronoPy/chronopy-hardware repository on GitHub, at the commit this page was made from: the board is chronopy.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Chronopy design in my own project?
Its repository states no licence, so its author keeps all rights: ask ChronoPy before reusing the design.
