This module is a 2 digit alphanumeric display with high brightness and red backlight, each digit is consists of a 14-segment digital tube. The commonly used 7-segment 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 alphanumeric display. The digit height is 0.54 inch and the red LED used in this module has super high brightness, so you can see it a few meters away. 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 on-board 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. We have released a lot of displays for Arduino, raspberry pi, Beaglebone and other SBC(Single Board Computer), now we bring you the Grove - 0.54" Red Dual Alphanumeric Display, the 14-segment display means more possibility and creativity. We hope it will help you create more interesting projects. Note We've Released the Grove Selection Guide and hope to help you find the Grove suits you best. Features Can display all letters and numbers Ultra-high brightness:30mcd Grove I2C, only takes two IO pins Onboard drivers, easy to use Cathode display Applications Display speed, temperature, etc. Letter display
