8x5 40 LED Matrix WS2812 LED 5050 RGB Full-Color Driver Board

product description description: ?The 2812 shield is stackable with an UNO board compatible design. The control circuit and RGB chip are integrated in a 5050 SMD component and are an intelligent control LED light source. It includes intelligent digital port data latch and signal shaping amplifier drive circuit. Also includes a precision internal oscillator and a 12V programmable constant current control section, effectively ensure a high degree of pixel color consistency. The data transfer protocol uses a single NZR communication mode. After a pixel power-on reset, the DI port receives data from the controller. The first pixel captures the initial 24-bit data and sends it to the internal data latch. specification: Anti-reverse protection circuit, reverse power supply will not damage the LEDs internal IC. The control circuitry and RGB chips are integrated in a 5050 SMD component to provide full pixel control. Each pixel of the three primary colors can achieve 256 brightness display, complete 16777216 color full-color display, the scanning frequency of not less than 400Hz / s Serial cascade interface, through the signal line to complete the receiving and decoding of data. No additional circuitry is required when the transmission distance between any two points does not exceed five meters. When the refresh rate of 30fps, the cascade number of not less than 1024 points. Data transmission speed can reach 800Kbps. The color of light is highly consistent and cost-effective. Size: approx. 6.9x 5.7x 1.9cm / 2.72x 2.24x 0.75inch Package includes: 1 pixel matrix mask note: Due to the difference between light and screen settings, the color of the item may be slightly different from the picture. Due to the different manual measurements, please allow a slight size difference.
