With all the libraries and examples prepared by sensirion and Adafruit, it was easy to connect it all together using the FeatherS2 and CircuitPython. A first prototype is connected and working.

Desing UROŠ - CO2 brkout PCB

PCB (printed circuit board) breakout board for CO2 sensor (SCD41), NEO-pixel (WS2812B) and I2C interface (JST-SH4)

Designed with open source software: Kicad, Inkscape and svg2shenzhen

The files "as ordered" are available on github: https://github.com/GenericLab/UROS-CO2_brkout
