A matrix display that consists of 117 RGB LEDs, 2x2 mm in size, in a 13x9 arrangement with a 3 mm raster. It uses analog LEDs controlled by PWM signals. An IS31FL3741 chip and two STEMMA QT/Qwiic connectors are placed on the board, allowing the user to control all the LEDs via the I2C bus. It is also possible to adjust the current of the driver, so the entire display can be brightened or dimmed without losing color resolution. The board can work with 3.3V to 5V power and logic. There are jumpers on the bottom of the PCB to configure the I2C address, which makes it possible to connect several displays to a single bus. The module is easy to use with libraries dedicated to Arduino and CircuitPython. Full documentation is available on the product page.
