## Description

**CoreInk Proto Base** is a DIY expansion kit suitable for CoreInk master control. When stacking the expansion board, the IO bus on the CoreInk main control will be led out to the PROTO board through the lower PIN pin. You can design and build the circuit according to your own needs. The package also contains a variety of expansion parts (HY2.0-4P female terminal, 3.96 male/female terminal, DC power terminal, etc.), which can be soldered to the PROTO board, which can add standard specifications to your circuit design. Output Interface. The hook hole on the back and the LEGO compatible hole design on the corners make it easy for you to embed the finished DIY product into a variety of structures.
