Highly scalable from a single 64-LED panel to a small LED wall, the bright red modules are suitable for displays with long-distance effects. The AZDelivery LED matrix with 256 LEDs consumes a maximum of only 160 mA, so that it can be conveniently operated without an additional energy source, e.g. via a microcontroller. The MAX7219 LED drivers are controlled via SPI data protocol using only 5 cables - even if you connect several modules together. Different effects can be achieved with different controllers: Spectrum music mode, rolling subtitle, image display, video display, fireworks effect and chase effect. Particularities Since the LEDs of the display are individually addressable, you can set the LEDs to scroll messages or show images on the display. Compared to other matrix displays, this display module is very cost-efficient and allows you to reduce the usage cost. The linkable and compatible design of the display allows expansion of the matrix panel. Technical specifications Dimensions 128 x 32 x 15mm Material PCB Chip Max7219 LED color Red Power supply From 3.3V to 5V DC Working current DC 30mA - 80mA Operating voltage From +3.3V to +5V DC Operating temperature from -10 ° C to 80 ° C Changeable brightness in software Brightness digital and analog Cost -effective design Made from high -quality materials, the Matrix display has a cost -effective and compact design and thus enables reduction in the costs.
