Questions
How big is the Zigbee air quality monitor PCB?
It measures 19.8 × 50.9 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Zigbee air quality monitor use?
35 parts, built around the BT840, SCD40-D-R2, TXS0102DCU and USBLC6-2SC6. 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 Zigbee air quality monitor KiCad files?
From the nobodyguy/zigbee_air_quality_monitor_hardware repository on GitHub, at the commit this page was made from: the board is zigbee_air_quality_monitor.kicad_pcb and its schematic zigbee_air_quality_monitor.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Zigbee air quality monitor design in my own project?
Its repository publishes it under the Apache-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
