Chain Bridge & Chain Return

M5Stack Chain Bridge and Chain Return are connectors designed for the chain series products and unit puzzles for extended connectivity and enhanced functionality integration. These bridges feature two interconnected HY2.0-4P grove interfaces. The chain return comes with two 4.85mm LEGO-compatible holes. The chain bridge connects adjacent chain series components, whereas the chain return allows the side edges. Typical applications include rapid prototyping, hardware interaction, education and learning, and DIY projects.
