An open-source, tiny (10.6x10.6mm) PCB with BME280 and SGP40 sensors. Runs on 3.3V power, communicates via I2C.

Designed by me for Nevermore Max 2 and StealthMax 3D printer air filters, assembled by me in the US.

I am the original creator of this project, and every sale here helps me fund the development of this and future open source PCB projects. Thanks!
