Usually 4 digit display module is a 12 pin module. But in our Crowtail gadget, we utilize a TM1650 to scale down the controlling pins into 2 Crowtail pins. It only takes 2 digital pins of Arduino or Crowduino to control the content, even the luminance of this display. For projects that require of alpha-numeric display, this can be a nice choice.
