M5Stack Chain Blank Proto with Chain Bridge

🔧 Chain Blank — Proto Board DIY Expansion Node

The Chain Blank is a Proto Board DIY expansion node in the M5Stack Chain series. On the front, it features an 18 × 18 mm universal prototyping area 🧩, perfect for building custom circuits. Inside, the PCB comes pre‑soldered with two interconnected HY2.0‑4P connectors 🔌, allowing seamless daisy‑chaining with other M5Stack Chain devices without affecting their original functionality.

When you need deeper DIY integration, the two 0 Ω resistors (R1 & R2) ⚡ that link the communication pins can be removed. This frees the IO pins for direct soldering or jumper‑wire connections 🛠️, enabling richer, more flexible interactive applications.
