Vendor:
This module is a 4-digit alphanumeric display with high brightness and red backlight, each digit consists of a 14-segment digital tube. The commonly used 7-segment display, such as the Grove - 4-Digit Display can only display the numbers 0-9 and a limited number of letters. In contrast, the 14-segment digital display does not have this limitation, it can display all the characters, that's why we call it an alphanumeric display.

7-segment display vs 14-segment display


The digit height is 0.54 inches and the red LED used in this module has super high brightness, so you can see it a few meters away.


0.54-inch Alphanumeric Display Height


Usually, the 14-segment display needs to use 17 or more wires to control the display, which means that a large amount of IO of your main control board (such as Arduino) will be occupied. With the help of the onboard HT16K33 chip and Grove connector, we made it an i2c display, only four wires are enough. No troublesome soldering and no complicated wiring, if you are using seeeduino, it is really plug-and-play, easy peasy.
