This is the NeoPixel Shield from Duinofun, an amazing Arduino shield. It comes with 40 WS2812 RGB LEDs arranged in a 5x8 matrix. You only need one pin (Digital #6) to control them all. The shield gets power from the 5V onboard Arduino supply. It works well as long as you don't light up all the LEDs at full - power white. You can also solder the included terminal block to connect an external 4 - 6VDC power supply if you need more power. You can chain multiple panels together when they are separated from the Arduino. For the second panel, connect the DIN to the first panel's DOUT, connect the ground pins, and power it with 5V. But note that if you're using an Arduino Uno, you may run low on RAM after chaining five or more panels. The package includes one NeoPixel Shield - WS2812 RGB LED Matrix. Check out the NeoPixel Überguide and NeoPixel Library for more information.
Using the Duinofun NeoPixel Shield is easy. First, connect it to your Arduino. You can control all 40 WS2812 RGB LEDs in the 5x8 matrix with just one pin (Digital #6). The shield is powered by the 5V onboard Arduino supply. However, if you want to light up all the LEDs at full - power white, it's better to use an external 4 - 6VDC power supply. You can solder the included terminal block to connect it. When you want to add more panels, connect the DIN of the second panel to the DOUT of the first one, link the ground pins, and power it with 5V. Just be aware that if you're using an Arduino Uno and chain five or more panels, you might run out of RAM. For maintenance, keep it in a dry and clean place. Avoid touching the LEDs with dirty hands as it may affect their performance. And always refer to the NeoPixel Überguide and NeoPixel Library for any additional questions.
