4-Digit 7-Segment Display
Sorry, currently out of stock
4-Digit Display module is a 12-pin module. In this module, we use 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 other mcu board. For projects that require alpha-numeric display, this can be a good choice.
Features
- 4 digit red alpha-numeric display
- Arduino compatible interface (3.3V/5V)
- 8 adjustable luminance levels
