Step 2: Connecting the Hardware

As stated before, working with SparkFun's Qwiic Connect System is very simple and this project will only require you to make 6 total connections. To one of the ESP32 Thing Plus boards (the transmitter or server board), we’ve connected the SparkFun Qwiic Environmental Breakout, and to the other ESP32 Thing Plus board (the receiver or client board), the Qwiic 20x4 SerLCD RGB Backlight Display. Note that since we’re only using the BME280 sensor from the environmental combo board, you could also use our Atmospheric Sensor Breakout - BME280 without any change to the code, if you would like to use that sensor board instead.

Our Qwiic components make projects like this incredibly fast and easy to set up.
