Founded in 2015, ELEGOO is a leading brand in the global smart manufacturing industry, specializing in R&D, manufacturing, and sales of consumer-grade 3D printers, laser engravers, STEM kits, and other smart technology products.
Located in Shenzhen, the Silicon Valley of China, we have grown to over 1000 employees with 42,000 square meters of office and manufacturing space.
Built on the open-source Arduino ecosystem, ELEGOO STEM Kits are designed to make hands-on learning accessible, engaging, and scalable for users of all ages. With a strong focus on modular design, complete step-by-step tutorials, and high expandability, ELEGOO has formed a three-tier STEM product matrix that supports everyone from first-time learners to advanced makers.
At the entry level, ELEGOO UNO R3 and Mega 2560 starter kits and ESP32 starter kits come with dozens to over 200 standardized electronic components and carefully structured learning guides. Users can quickly build circuits without soldering and learn C/C++ programming through practical projects with fully open and editable source code. This low barrier to entry makes it easy for beginners to build solid foundations in electronics and programming.
For advanced users, ELEGOO’s intelligent robot kits include smart cars, self-balancing robots, FPV robot tanks, and more. These kits support obstacle avoidance, line tracking, visual recognition, and dual control via mobile app and infrared remote. Selected models are also compatible with LEGO building blocks, enabling deeper exploration of motion control, robotics, and machine vision while keeping learning both technical and fun. A wide range of supporting accessories—such as multicolor Dupont wires, solderless breadboards, and expansion boards—further enables flexible project development and creative customization.
ELEGOO STEM Kits have earned strong global recognition for both educational value and commercial performance. The brand ranks as a top Arduino-category seller on Amazon, with over 50% repurchase rate and multiple editor awards. Today, ELEGOO STEM products are used in more than 70 countries and adopted by over 70 universities and research institutions for teaching and project-based learning in robotics, aerospace, and engineering.
Continuous innovation is at the core of the product line. Based on user feedback, ELEGOO regularly upgrades hardware and tutorials, such as integrating sensor shield designs into UNO kits for easier wiring, and releases highly integrated Mega kits featuring 200+ components and 33 guided projects for a smoother learning experience.
Looking forward, the integration of ELEGOO STEM Kits with 3D printing technology unlocks a powerful cross-disciplinary ecosystem. Students can design and print custom mechanical structures before implementing electronic control. Makers can break free from standardized components through non-standard printed parts. Families can turn coding into hands-on creative play. Advanced developers can rapidly prototype functional devices with customized enclosures. Together, STEM Kits and 3D printing form a complete “design–build–program–iterate” innovation loop, empowering users to turn ideas into real-world creations faster than ever.

This tutorial is designed specifically for beginners. You will first systematically master the core basic knowledge of ESP32 development boards, individual sensors, and components. Building on this foundation, you will gradually learn to integrate multiple components to complete combined projects. As the learning difficulty progresses, you will also use Wi-Fi and Bluetooth functions to implement more advanced projects. In addition, the content of this tutorial has good scalability, which can adapt to more cutting-edge application scenarios with the iteration of future firmware and hardware versions.
