Product description: 0.54'' 4-character alphanumeric display - red - STEMMA QT / Qwiic - Adafruit 1911

The alphanumeric display, manufactured by Adafruit, was 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 red and visible at a distance of up to 7 meters. There are also 4 dots on the module, one 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!
