This module is an LED display driver module composed of 4 8 * 8 dot arrays, each with a separate MX7219 driver IC. In addition, it can communicate with other controllers through SPI (Serial Peripheral Interface) and control up to 64 individual LEDs to display different effects, such as animation and text flow images. It is widely used in various public places, such as car stop announcements, advertising screens, and billboards.
