1、The three primary colors of each pixel can achieve 256 levels of brightness display, complete 16777216 kinds of colors for true color display, and the scanning frequency is not less than 400Hz/s. 2、LED has the advantages of low voltage drive, environmental protection and energy saving, high brightness, large scattering angle, good consistency, ultra‑low power and long life. 3、Intelligent reverse connection protection, power reverse connection will not damage the IC, the control circuit and LED share the only power supply. 4、When the refresh rate is 30fps, the number of cascades is not less than 1024 points, and the data transmission speed is 800Kbps. 5、You can set each LED as needed to scroll messages or draw small images. The color of the light is highly consistent and cost-effective. 1 x Development Board Item Type: LED Development BoardMaterial: PCBPurpose: Suitable for college students, engineers, technicians, factories, individual DIY, electronic enthusiasts and other operation learning.Size: Approx. 71x71mm/ 2.8x 2.8inWorking Voltage: 5V DCInterface: IORGB Quantity: 8 x 8 (64 RGB)Chip: WS2812bBeam Angle: 180°Luminous Color: Can be adjusted to white, red, yellow, blue, green, etc. by the controller
