NeoPixel Shield- WS2812 RGB LED Matrix
This is the NeoPixel Shield from Duinofun. This Arduino shield is equipped with 40 WS2812 RGB LEDs arranged in an 5x8 matrix with on one pin (Digital #6) needed to control them all.
Each shield is powered by the 5V onboard Arduino supply and as long as you aren’t lighting up all the LEDs full power white that should be fine. 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.
