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