You can find more information and the latest firmware at attno.de v3. @seiichiro0185 is continuously developing the software, which is why it is only linked here.

This pcb allows the extension of the attno.de v3 with the possibility to be operated with 5V-15V operating voltage as well as CO2 measurement by means of MH-Z19.
