Questions
How big is the Mics6814 qwiic PCB?
It measures 25.4 × 17.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Mics6814 qwiic use?
26 parts, built around the MICS-6814, 74HC1G04GW and ADS1115. 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 Mics6814 qwiic KiCad files?
From the jdexyz/SimpleAirQualitySensor repository on GitHub, at the commit this page was made from: the board is mics6814/mics6814_qwiic/mics6814_qwiic.kicad_pcb and its schematic mics6814/mics6814_qwiic/mics6814_qwiic.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Mics6814 qwiic design in my own project?
Its repository states no licence, so its author keeps all rights: ask jdexyz before reusing the design.
