Hardware Assembly

Now that we're familiar with the hardware on this Qwiic breakout, let's assemble it into a Qwiic circuit and start getting environmental data from the STC31.

Qwiic Assembly

The Qwiic system allows solderless connections for power and I2C so all you need to get up and running is a Qwiic cable and Qwiic compatible development board (or a Qwiic adapter cable). Assemble your Qwiic circuit by connecting the CO2 Sensor - STC31 to your development board with the Qwiic cable and then connecting the development board to your computer over USB like the photo below shows:

Soldered Assembly

Users who prefer a traditional soldered assembly should solder wires or header pins to the PTH header on the side of the board. If you're not familiar with through-hole soldering or would like a refresher, take a look at our Through-Hole Soldering Tutorial.
