- the scd4x sensor can draw up to 205ma peaks at 3.3V (only 18ma average) so make sure you have a robust power source (the above schematic has been tested to work)
- you only need to solder the 6 pins shown and the thermal pad on the underside to get it working
- unfortunately I have not found a way to easily solder these sensors with a soldering iron, a oven or hotplate seems to be the only way
