This matrix of 16 x 32 RGB LEDs brings big city feeling to the living room. The panels are usually used in video walls, e.g. as a billboard on house walls, bus stops, etc. You can view short animations and videos. The 512 bright RGB LEDs are arranged in a 16x32 grid on the front. On the back there is a PCB with two IDC ports (1x input, 1x output) and 12 16-bit slide registers that allow you to control the display at a 1:8 sampling rate. The displays can be switched in series - for this purpose, the output of the first display is connected to the next input. Adafruit sample code does not (yet) support this. In this case, Arduinos do not have the required processor power and the required RAM. These display panels require 12 digital pins (6 data and 6 control lines) and a good 5V power source with up to 2A per panel. Please remember that these displays are actually intended to work on FPGAs or other high-speed processors: they do not have any built-in PWM control. Instead, you have to replay the display again and again and thus simulate PWM control. On a 16MHz Arduino, Adafruit has succeeded in achieving 12-bit colour depth (4096 colours) at 20% CPU usage. The full performance of the display is only achieved on an FPGA, CPLD, Propeller, XMOS or other high-speed multicore controller. The Adafruit Learning Center has great tutorials and wiring diagrams that provide a good foundation for using this product. Please note that this product may vary from batch to batch in appearance and size. The operation remains the same.
