This is a module that integrates two 8x8 dot matrix screens, supporting the display of letters, expressions, patterns, and more. The 4Pin alligator clip interface is designed on the bottom of the dot matrix, the 4Pin pin header interface is designed on the back, and the 4Pin DuPont line interface is reserved on the front side (the default is not soldered). Users can use these interfaces to match the alligator clip, cable, DuPont line, and other electronic Device to complete IIC communication. It also has two building block pinholes, which are compatible with LEGO building blocks to match different interesting structure shapes.
