Adafruit DotStar digital LED strip, 144 LEDs / m, 0.5m, black

The chic new DotStar LED bars are a great upgrade for people who have loved and used NeoPixel bars for a few years, but want something better. DotStar LEDs use generic 2-wire SPI. This makes it possible to transfer data much faster than with the NeoPixel 800 KHz protocol, without specific timing. In addition, you have a significantly higher PWM rate, so that you can implement Persistence-of-Vision (POV) with less flicker, especially with lower brightness levels.

DotStar-Leds are like NeoPixel LEDs of size 5050 with a microcontroller embedded in the LED. You can set the color and the brightness of each LED with a resolution of 24-bit (each 8-bit red, green and blue). Each LED works like a shift register, which reads incoming color data at the input pins and then shifts out the previous color data at the output pin. 
It is possible to control an infinite number of LEDs by adding more LEDs or cutting off unwanted LEDs. The PWM is integrated in all LED chips, so that after setting the color you no longer have to communicate permanently with the LED bar and the PWM of the individual LEDs remains. 

These LEDs, unlike the NeoPixels, have two wires (input and output) for sending data - a data line and a clock line. Two pins are required for this to control the DotStars. Any processor gate speed and any processor type can be used to drive the strips. So you don't have to worry about timing anymore. Hardware SPI support is useful but not required. Because of this, they're great for use with any microcontroller or microprocessor, including Arduino, Raspberry Pi, BeagleBone, Propeller, SparkCore, and Allen "raw" microcontroller / microprocessor. Porting the library is very simple. You can send data to the pixels at a clock rate of up to 32 MHz! 

Another plus point with DotStars is the high PWM rate. You only have to set the 24-bit color data once for each pixel LED. Then the LED and the built-in chip take over the PWM of red, green and blue. With NeoPixels, this happens at a PWM rate of 400 Hz, which works well. However, the low frequency is noticeable at low brightness and when the bar is moved. DotStars have a PWM rate of 20 KHz. 

The product is an LED strip with a length of 0.5m.

The bar is made of flexible PCB material and is supplied with a weatherproof cover. You can easily cut the material with scissors and separate each individual LED. Of course, the strips can be connected to one another. To extend it, just pay attention to how much power you need!
You need a 5V DC power supply to operate these strips. Please note that the voltage must not be higher than 6V, otherwise you can destroy the entire bar.

The strip comes as a single half meter with a 4-pin JST-SM connector on each end. If you buy several, you will receive several 0.5 meter strips. To wire these strips, it is recommended to get some JST-SM male and female cables for the signal lines.
