Description
Chain Blank is a Proto Board DIY expansion node in the M5Stack Chain series. The front side of the node provides an 18 x 18mm universal PCB prototyping area. Inside, two interconnected HY2.0-4P connectors are pre-soldered, allowing it to be directly daisy-chained with M5Stack Chain series devices without affecting the original device functionality. When DIY integration of custom circuits is required, the two 0Ω resistors that connect the communication pins R1 and R2 on the Chain Blank PCB can be removed. The IO pins can then be connected to other circuits via soldering or jump wires, enabling the creation of richer and more flexible interactive applications.
