This product is discontinued, and here's the updated version instead: Ultrathin 16x32 RGB LED Matrix Panel.
The ultra light and ultra thin LED matrix panel we have ever seen! It consists of one fully assembled panel and a 10 pin IDC cable. There are 512 bright red LEDs on the panel. Large view angle makes the brightness never decay when watching from the side. The panel module is also chainable, which can be connected together to make an extra long display. You may need an microcontroller to control this display, such as an Arduino Uno shown in the following image:
