This is the NeoPixel Shield from Duinofun. This Arduino shield is equipped with 40 WS2812 RGB LEDs arranged in a 5x8 matrix with only one pin (Digital #6) needed to control them all. Each shield is powered by the onboard 5V Arduino supply and as long as you don't light up all the LEDs, all white will suffice. You can also solder in the included terminal block to attach an external 4-6VDC power supply in case you need more power than what the Arduino provides. Additionally, you can tile as many of these panels together as you like as they are tiled separately from the Arduino. For the second panel, connect the DIN connection to DOUT of the first panel, connect the ground pins together and power it with 5V. It should be noted that after five or more panels you will run out of RAM if you are using an Arduino Uno .
