v3

Baseline release of the AirGradient SGP41 TVOC sensor module — the version in production use.

A compact 2-layer carrier board for the Sensirion SGP41 TVOC/NOₓ sensor, exposing the sensor's I²C interface on a 4-pin 2.54 mm header with on-board pull-ups and decoupling. Used in AirGradient air quality monitors, including the Open Air Max.

Attached: tvoc-sensor-module-v3.zip — the released Gerber production set (the Gerber filenames keep the design's original tvoc-sensor-module naming). The BOM is tracked in the repository under sgp41-tvoc-sensor-module/BOM/.

Design files are in KiCad 6 format and open in KiCad 6 or newer with no extra library setup.
