The u-blox NEO-M8U is a powerful GPS units that takes advantage of untethered dead reckoning (UDR) technology for navigation.

Looking to keep a log of the climate in your greenhouse, create a humidor control system or want to track temperature and humidity data for a weather station project? The SparkFun Humidity Sensor Breakout - SHTC3 (Qwiic) may be the perfect option for you!

The SparkFun Environmental Sensor - BME680 (Qwiic) is a breakout for the 4-in-1 BME680 gas sensor from Bosch. The BME680 combines a gas sensor with temperature, humidity and barometric pressure sensing for a complete environmental sensor in a single package.

In this tutorial we'll detail the hardware on the Dual Solid State Relay, how to connect it to an Arduino or other microcontroller and how to use the examples included in our Arduino library and Python package.

In this guide we'll go over everything you need to know about the Qwiic GPIO so you can add those extra I/O pins to your circuit with ease!

Introducing the SparkFun QwiicBus system! The QwiicBus is a fast and easy way to extend the range of your I‎²‎C bus.
