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 18mm universal prototyping area , perfect for building custom circuits. Inside, the PCB comes presoldered with two interconnected HY2.04P connectors , allowing seamless daisychaining with other M5Stack Chain devices without affecting their original functionality.

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