Questions
How big is the CSL AQS V5 PCB?
It measures 165.1 × 54.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the CSL AQS V5 use?
262 parts, built around the BME280 and TPS61023DRL. 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 CSL AQS V5 KiCad files?
From the Community-Sensor-Lab/Air-Quality-Sensor repository on GitHub, at the commit this page was made from: the board is Contents/E_CAD-KiCad/CSL_AQS_V5.kicad_pcb and its schematic Contents/E_CAD-KiCad/Adafruit-Adalogger-FeatherWing.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the CSL AQS V5 design in my own project?
Its repository publishes it under the GPL-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).
