WS2812 5050 RGB LED Driver Module Square Board 16 LED

From Makers Electronics's description

This 4×4 RGB full-color LED matrix module is based on WS2812 intelligent control LEDs. Each LED can be independently addressed with RGB pixels that can achieve 256 levels of brightness. That’s 16777216 colors in total with a scanning frequency no less than 400Hz! The 8×8 RGB LED Matrix is single wire control board. The module also supports cascading control. All you need to do is connect Din to the DOUT port. In combination with the open source Arduino library, you can control an entire array of LEDs using just one pin! Note: Each LED requires a maximum current of 18mA. When multiple modules are in use, it is recommended to use external power supply to power multiple LEDs matrix. Features: The control circuit and the LED share the only power source. The control circuit and RGB chip are integrated into a package of 5050 components, forming a complete control of pixel points. Built-in signal reshaping circuit, after wave reshaping to the next driver, ensures wave-form distortion does not accumulate. Built-in electric reset circuit and power lost reset circuit. Each pixel of the three primary colors can achieve 256 brightness levels, or 16M colors full-color display, and scan frequency not less than 400Hz/s. Cascading port transmission signal by a single line. Any two points the distance of more than 5m transmission signal without any increase circuit. When the refresh rate is 30fps, the cascade number is not less than 1024 points. Send data at speeds of 800Kbps.
