4 digit display module is usually a 12 pin module. In this Grove gadget, we utilize a TM1637 to scale down the controlling pins into 2 Grove pins. It only takes 2 digital pins of Arduino or Seeeduino to control the content, even the luminance of this display. For projects that require of alpha-numeric display, this can be a nice choice.
