Sparkfun Electronics

This tutorial will guide you through using the SparkFun MOSFET Power Switch and Buck Regulator (Low-Side) with your Arduino projects.

The SparkFun Temperature Sensor - STTS22H (Qwiic) and the SparkFun Micro Temperature Sensor - STTS22H (Qwiic) are Qwiic enabled breakout boards based on the ultralow-power, high-accuracy, digital temperature sensor STTS22H from ST Microelectronics.

The RTK Reference Station from SparkFun is our most capable GNSS receiver and logger to date.

The MicroMod STM32WB5MMG Processor expands on SparkFun's MicroMod ST product line with a powerful combination of computing and wireless capabilities all on one Processor.

The SparkFun Arduino UNO R4 WiFi Qwiic Kit is a great way to get started with Arduino and the Qwiic-connect system.

The SparkFun Air Quality Sensor - SGP40 (Qwiic) is a robust metal oxide (MOx) based indoor air-‎quality measurement tool using the SGP40 gas sensor from Sensirion.
