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.

SparkFun ProDriver and Mini Stepper Motor Driver utilize the latest TC78H670FTG stepper motor driver from Toshiba. With two different methods for control (serial communication or clock-in stepping) this is a great option for your next project that requires precise motor control.

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.

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