Hardware Assembly

Let's go ahead and wire this up in a Qwiic circuit to start using the SFA40.

Qwiic Assembly

Since thi is a Qwiic breakout, all we need to do is plug it into a Qwiic-comaptible development board, like the RedBoard IoT shown below, with a Qwiic cable. After that, plug the RedBoard into a computer over USB-C and we can move on to using the SparkFun SFA40 Arduino library to get data from the sensor:
