DFRobot was founded in 2008, among the first to embrace open source hardware, After a decade, DFRobot has expanded from open source hardware to STEM education, AIoT, and other high-tech industries. Our mission is to form a community with easy access to whether hardware, software and ideas that allow makers and younger generation to achieve their goals and realize creative ideas in an effective manner.
STEM Education
Since 2013, DFRobot began to create STEM education kits and comprehensive learning resources including hardware, software, content solutions for students to engage with in the classroom, which allow students to benefit from creation, in identifying their own challenges, solving new problems, motivating themselves to working together, inspiring and sharing with others. We believe making and creating get our younger generation
closer to the future, and one day they will change the world with what they make.
