Notify me when its in stockDotStar LEDs use a 2-wire SPI, allowing you to transmit data much faster than the NeoPixel's 800 KHz protocol, and they don't require precise timing. They also have much higher PWM refresh rates, allowing you to do Persistence of Vision (POV) and have less flicker, especially at low brightness levels.
Unlike NeoPixels, DotStar LEDs have 2 wires (input and output) for data transmission—a clock pin and a data pin. This means you need two pins to control DotStars. Since the clock and data are separate, you can use any processor speed or type to control these strips without worrying about timing. Hardware SPI support is helpful but not required. This makes them perfect for use with any microcontroller or microprocessor, including Arduino, Raspberry Pi, BeagleBone, Propeller, SparkCore, and any 'raw' microcontroller/microprocessor. It's easy to port the library, and you can send data to the pixels at up to 32MHz!
Another great feature of DotStars is their high PWM rates. You only need to set the 24-bit color data for each pixel LED once, and then the built-in chip handles the PWMing of the red, green, and blue. NeoPixels have a PWM rate of 400 Hz, which works well, but it's noticeably lower in brightness at low levels and when the strip is moving. DotStars have a 20 KHz PWM rate, so you won't see any flickering even when moving the strip, and color mixing is very smooth.
The strip is made of flexible PCB material and comes with a weather-resistant casing. You can easily cut these strips with wire cutters; there are cut lines every 1 LED. Solder to the 0.1" copper pads, and you're ready to go.
To power these strips, you should use a 5V DC power supply, and do not exceed 6V, or you might damage the entire strip.
If you're using our DotStar library, you'll need to change the type you're using. Check the tutorial for details on how to do this! The LED colors are otherwise the same; you just need to send the data in a slightly different order.
Note : Strips come with 4 solder points per segment, but the arrangement may vary depending on the supplier, so please check during soldering/powering!
