Grove - 0.54" Red Dual Alphanumeric Display

This is a red backlit 2-digit alphanumeric display, each digit consists of a 14-segment. The popular 7-segment displays can only display the numbers 0-9 and a limited number of letters. These 14-segment digital displays do not have this limitation, they can display all the characters, that's why it's called an alphanumeric display.

Usually, the 14-segment display needs to use 17 or more wires to control the display which means that a lot of IO pins are used on your main control board. With the help of an onboard HT16K33 chip and Grove connector, this display can be controlled using I2C. This means only four wires are required! No troublesome soldering and no complicated wiring!
