This 830-point breadboard is fully compliant with RoHS environmental standards, adopting non-toxic, eco-friendly and high-quality materials that meet the safety requirements of campus teaching scenarios. It is specially designed for campus STEM education, aiming to provide a convenient and safe experimental platform for teachers and students. The breadboard is equipped with reasonably distributed holes, which can perfectly match common electronic components such as resistors, capacitors and sensors, and supports hot swapping of components without soldering, greatly reducing the operation difficulty. It is widely used in campus teaching, after-school practice and STEM competition activities, suitable for electronic teachers to carry out teaching demonstrations, students to complete practical operations, and STEM education practitioners to carry out experimental guidance. It not only meets the needs of daily teaching and practical training, but also helps improve students' hands-on ability and logical thinking ability, becoming an indispensable core experimental tool for campus STEM education and after-school practice.
