Hardware Assembly

Arduino Examples

With the Qwiic connector system, assembling the hardware is simple. All you need to do is connect your Qwiic Atmospheric Sensor (BME280) to the RedBoard Qwiic with a Qwiic cable. Otherwise, you can use the I2C pins of your microcontroller; just be aware of logic levels.

Note: This tutorial assumes you are familiar with Arduino products and you are using the latest stable version of the Arduino IDE on your desktop. If this is your first time using the Arduino IDE, please review our tutorial on installing the Arduino IDE.

Raspberry Pi Example

Note: This sensor and the Python library have not been tested on the newly released Raspberry Pi 4 because we don't carry it in out catalog yet.

With the Qwiic connector system, assembling the hardware is simple. In addition to the Qwiic Atmospheric Sensor (BME280), you will need: a Qwiic cable, a SparkFun Qwiic pHAT for Raspberry Pi, and a Raspberry Pi setup with the Raspbian OS, monitor, and standard peripherals. (*If you are unfamiliar with the Qwiic pHAT, you can find the Hookup Guide here.)

Hardware assembly with Raspberry Pi 3B+ with Qwiic pHAT
Raspberry Pi 3B+ connected the Qwiic Atmospheric Sensor with a Qwiic pHAT and Qwiic cable.
(*A 4-40 screw and nut were used to mount the senor to the pHAT.)

Alternatively, you can also use a Raspberry Pi 3 and the Qwiic HAT instead.

Note: This tutorial assumes you are familiar with using a Raspberry Pi and you have the latest (full... with recommended software) version of Raspbian OS your Raspberry Pi. You can download the latest version of the Raspbian OS from the Raspberry Pi Foundation website. As of Feb. 13th 2019, we recommend the Raspbian Stretch with desktop and recommended software option.

If this is your first time using a Raspberry Pi, please head over to the Raspberry Pi Foundation website to use their quickstart guides. We have listed a few of them here:
