M5Stack Chain Blank

M5Stack Chain Blank is a Chain series Proto Board Do-It-Yourself (DIY) expansion node. The front side of the node provides an 18mm x 18mm universal PCB prototyping area. Inside the node, two interconnected HY2.0-4P connectors are pre-soldered. The pre-soldered connectors allow the node 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 M5Stack Chain Blank PCB can be removed. The I/O pins can then be connected to other circuits via soldering or jump wires, enabling the creation of richer and more flexible interactive applications.
