WS2812B Rectangular Full Color RGB LED Module [40 Bit]

Description:
This is the NeoPixel Shield from Adafruit. This Arduino shield is equipped with 40 WS2812 RGB LEDs arranged in a 5x8 matrix with 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.
Additionally, you can chain as many of these panels together as you would like when tiled separately from the Arduino. For the second panel, connect the DIN connection to the first panel's DOUT, connect the ground pins together and power with 5V. It should be noted that after five or more panels you may run low on RAM if you are using an Arduino Uno.
WS2813B is an intelligent external control LED light source that integrates the control circuit and light-emitting circuit. Its appearance is the same as a 5050 LED lamp bead, each element is a pixel. 
The pixel contains a smart digital interface data latch signal shaping amplifier driving circuit, and also contains a high-precision internal oscillator and a 12V high-voltage programmable constant current control section, which effectively ensures that the color of the pixel light is highly consistent.

Specifications:
Intelligent reverse polarity protection, power supply reverse polarity will not damage the IC.
IC control circuit and an LED light source utility power.
The control circuit and RGB chip in a 5050 package of components constituting complete external control pixels.
Built-in signal shaping circuit, any one pixel after receiving the signal through the waveform shaping and then output to ensure line waveform distortion will not accumulate.
Built-in power-on reset and brown-out reset circuit.
Trichromatic color of each pixel enables 256 brightness display, complete 16777216 colors full true color display, scanning frequency of not less than 400Hz/s.
Serial cascade interface, through a signal line, finishes receiving and decoding data.
Pass any two points in the transmission distance of not more than 5 meters without any additional circuitry.
When the refresh rate of 30 frames/sec, the number of cascades of not less than 1024 points.
Data transmission speeds of up to 800Kbps.
Light color highly consistent, cost-effective.
