Hardware Assembly

With the SparkFun Qwiic system, assembling the your sensor circuit is easy! All you need to do is connect your SparkFun Air Quality Sensor - SGP40 (Qwiic) to your chosen development board with a Qwiic cable or adapter cable. If you would prefer to not use the Qwiic connectors, you can connect to the 0.1" header pins broken out on bottom of the board.

If you decide to use the PTH pins broken out on the Air Quality Sensor you need to solder to them or if you want a temporary connection for prototyping, these IC Hooks are a great option to make that connection. If you are not familiar with through-hole soldering take a look at this tutorial:
