SparkFun has been a go-to source for electronics hobbyists and engineers since 2003. Founded by Nathan Seidle while he was a student at the University of Colorado, the company started as a small online shop selling breakout boards and has grown into a major player in the maker electronics space.
SparkFun’s specialty is making complex components accessible. Many sensors and chips come in tiny, hard-to-solder packages that are impractical for prototyping. SparkFun designs breakout boards that mount these components on larger, easier-to-use PCBs with clear pin labels and mounting holes. This approach has made thousands of components available to people who don’t have surface-mount soldering skills.
The company designs many of its own products and publishes the designs as open-source hardware. SparkFun’s catalog includes microcontrollers, GPS modules, IMUs, environmental sensors, displays, motor drivers, and complete project kits. The company’s Qwiic Connect system uses standardized I2C connectors that let you chain sensors and boards together without soldering.
SparkFun’s educational content is a major part of its identity. The company’s tutorials cover fundamental electronics concepts, specific product guides, and complete project walkthroughs. SparkFun also runs workshops, supports classroom programs, and creates educator-focused kits.
Based in Boulder, Colorado, SparkFun operates from a large facility that includes offices, a warehouse, and manufacturing space. The company has shipped products to hobbyists, schools, and companies in over 100 countries. SparkFun remains privately held and continues to focus on making electronics fun and accessible for everyone from beginners to experienced engineers.
