SparkFun Electronics is an open-source hardware company founded in 2003 by Nathan Seidle in Boulder, Colorado, focused on making electronics and embedded systems accessible to makers, educators, and engineers. The company designs its own line of breakout boards, development kits, sensors, and learning platforms while also carrying components from Arduino, Raspberry Pi, and other ecosystem partners. SparkFun is credited with helping build the modern maker movement by making electronic components easy to find and use.

The SparkFun online store stocks thousands of electronic components, microcontrollers, 3D printing accessories, robotics parts, and tools. The company's extensive free tutorial library covers everything from basic soldering to advanced IoT projects, and its educator discounts and classroom kits make it a popular choice for STEM education programs. SparkFun's in-house designed products feature detailed hookup guides and open-source designs that users can modify and build upon.
