Description

4-Digit Display module is a 12-pin module. In this module, we use a TM1637 to scale down the number of controlling pins to 2. That is to say, it controls both the content and the luminance via only 2 digital pins of Arduino or other mcu board. For projects that require alpha-numeric display, this can be a good choice.
