NeoPixel Ring - 12 x WS2812 5050 RGB LED Ring Board for Arduino Raspberry Pi

NeoPixel Ring - 12 x WS2812 5050 RGB LED Ring Board for Arduino Raspberry Pi
Round and round and round they go! 12 ultra bright smart LED NeoPixels are arranged in a circle with 1.5" (37mm) outer diameter. The rings are 'chainable' - connect the output pin of one to the input pin of another. Use only one microcontroller pin to control as many as you can chain together! Each LED is addressable as the driver chip is inside the LED. Each one has ~18mA constant current drive so the color will be very consistent even if the voltage varies, and no external choke resistors are required making the design slim. Power the whole thing with 5VDC and you're ready to rock.
1. Intelligent reverse polarity protection, power supply reverse polarity will not damage the IC.
2. IC control circuit and a power LED spot light utility.
3. Control circuit chip with RGB components in a package in 5050, to form a complete external control pixels.
4. 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.
5. Built-in power-on reset and brown-out reset circuit.
6. Serial cascade interface, through a signal line to complete the receiving and decoding of data.
7. Transfer transmission distance between any two points in less than 5 meters without any additional circuitry.
8. The color of the light highly consistent, cost-effective.
