4 digit display module is usually a 12 pin module. In this Grove module, 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 the alpha-numeric display, this can be a nice choice.
Tip
We have released two 14-segment digital display, the Grove - 0.54?? Red Quad Alphanumeric Display and the Grove - 0.54" Red Dual Alphanumeric Display They can display all the letters, their scope of application is much wider than this one.
