Name: One WS2812B Full Color LED Module Size: 14*12mm Chip: WS2811 (built in LED) LED:5050 package RGB full color highlight Voltage: 5V Port: Number Platform: Arduino Microcontroller 5050 bright LED, built-in control chip, only need one IO port to control multiple LEDs Built-in shaping circuit in the chip, signal distortion will not accumulate, stable display Three primary color 256 brightness adjustments, 160,000 colors true color display effect, scanning frequency not lower than 400Hz/S Serial level interface, data reception and decoding can be completed through a single signal line When the refresh rate is 30 frames/second, the number of consecutive stages in the low-speed cascade mode is not less than 512 points. Data transmission and receiving speed up to 800Kbps High-brightness LED with high brightness and lightness Both ends have a serial interface that can be plugged directly Package Contents: 1*WS2812B WS2811 RGB 5050 LED 1Bit Module Board For arduino 5PCS WS2812 5050 There is a single data line with a very timing-specific protocol. Since the protocol is very sensitive to timing, it requires a real-time microconroller such as an AVR, A rduino, PIC, mbed, etc. It cannot be used with a Linux-based microcomputer or interpreted microcontroller such as the netduino or Basic Stamp. Features: Chip: WS2812 (built-in LED) LED:1pcs 5050 RGB full color highlighting Voltage: 5V Ports: Digital Platform: Arduino microcontroller Applications: Full-color module, Full color soft lights a lamp strip. LED decorative lighting, Indoor/outdoor LED video irregular screen.
