Description Chain Bridge Connector is designed for M5Stack Chain series products and Unit Puzzle assemblies. It provides two interconnected HY2.0-4P Grove interfaces, allowing adjacent Chain series components to be linked in a compact, repeatable layout. The connector helps expand the flexibility of the M5Stack module system without adding active circuitry. For developers building control panels, sensor chains, classroom hardware, or DIY interaction devices, the Chain Bridge Connector keeps nearby modules aligned while passing the Grove-style signal lines through cleanly. Each pack includes ten compact bridge connectors, giving projects enough parts for multi-node layouts, spare hardware, and repeated experiments. The durable body and small footprint make the Chain Bridge Connector useful for rapid prototyping, hardware interaction, education, learning, and custom module arrangements. Features Chain Bridge Connector design: links adjacent Chain series products and Unit Puzzle modules. Dual Grove interfaces: two interconnected HY2.0-4P Grove ports carry the pass-through connection. Simple pin map: routes GND, 5V, IO1, and IO2 for predictable modular wiring. Pack quantity: supplied as a 10-piece set for multi-module layouts and spares. Use cases: rapid prototyping, hardware interaction, education, learning, and DIY projects. Specifications Connector type Chain series adjacent bridge connector Interfaces 2 x interconnected HY2.0-4P Grove interfaces Pin mapping GND, 5V, IO1, IO2 Connector size 14.0 x 10.0 x 9.3mm Connector weight 11.0g for 10 pieces Package size 93.0 x 138.0 x 10.0mm Gross weight 14.0g Applications Chain Bridge Connector layouts for joining adjacent Chain series components. Rapid prototyping with Chain series controls, sensors, and Unit Puzzle structures. Education and learning kits that need repeatable connector hardware. DIY projects where compact Grove signal pass-through helps keep the build tidy. Product List 10 x Chain Bridge Other Content The HY2.0-4P pin map uses Black for GND, Red for 5V, Yellow for IO1, and White for IO2. This pass-through arrangement keeps Chain series wiring easy to trace when several modules are placed side by side. The connector is intended for adjacent mechanical and electrical connection, not signal processing. Use the schematic and model size files to confirm routing, dimensions, and installation space before a fixed enclosure or teaching kit is finalized.
