The module with the I2C controller based on the HT16K33 system. It is dedicated to alphanumeric 7-segment displays. The module does not have a built-in display, so the user can choose its color to suit his own design. The board is equipped with two STEMMA QT connectors, which greatly facilitates the connection of development kits. Modules can be stacked to form larger matrices. The manufacturer provides the Arduino library with examples together with the driver.
