Product description: 0.54'' 4-character alphanumeric display - blue - STEMMA QT / Qwiic - Adafruit 1912
Alphanumeric display by Adafruit, based on the HT16K33 controller. The diagonal of the display is 0.54'' , and the resolution is 4 characters (numbers from 0 to 9, letters from A to Z) presented in blue . There are additional 4 dots on the screen, which are located directly behind each segment. The module for communication uses a bidirectional I2C bus , has built-in STEMMA QT / Qwiic connectors for easy connection of the module without the need for soldering. Segments and connectors should be soldered into the board by yourself.
The manufacturer has also prepared a detailed user guide - check it out!
0.54'' 4-character alphanumeric display - blue - STEMMA QT / Qwiic - Adafruit 1912.
The board has leads in the form of solder pads and convenient STEMMA QT / Qwiic connectors.
Pins of the segment display module
The module communicates with the microcontroller via the I2C interface, on the board you can also find 2 Qwiic / STEMMA QT connectors for quick connection to modules equipped with the same connector. The supply voltage is 3 V or 5 V.
