1. Introduction
Grove - 4-Digit Display module is a 12-pin module. In this module, we utilise 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 Seeeduino. For projects that require alpha-numeric display, this can be a nice
choice.
