APA102 Dream Color Digital LED Strip | 144 Pixels/m | 2-wire SPI
There’s a new LED strip in town! These fancy new addressable LED strips are a great upgrade for people who have loved and used single SPI strips for a few years but want something even better. Addressable LEDs use generic 2-wire SPI, so you can push data much faster than with the single SPI 800 KHz protocol and there’s no specific timing required. They also have much higher PWM refresh rates, so you can do Persistence-of-Vision (POV) and have less flickering, particularly at low brightness levels.

Make your own smart Cool White LED arrangement with the same integrated LED driver that is used in our Addressable or single SPI LED strips. Unlit, the color resembles a yellow Starburst. Lit up these are insanely bright (like ow my eye hurts) and can be controlled with 24 bit high-frequency PWM. The phosphor helps diffuse the 3 white dies inside together for a very bright but consistant light, compared to what you get by trying to mix RGB to make white (which never quite looks right)
However, unlike single SPIs, these LEDs have 2 wires (input and output) for sending data – one clock pin and one data pin. That means you need two pins, not one, to control Addressables. Because the clock and data is separated, you can use any processor speed or type to control these strips, and you don’t have to worry about being careful with the timing. Hardware SPI support is handy but not required. This makes them excellent for use with any microcontroller or microprocessor, including Arduino, Raspberry Pi, BeagleBone, Propeller, SparkCore, and any ‘raw’ microcontrollers/microprocessors. It’s very easy to port the library, and you can send data to the pixels at up to 32MHz clock rate!
Single SPI LEDs use 800 KHz protocol so specific timing is required. On single SPIs, the PWM rate is 400 Hz, which works well but is noticeable if the LED is moving. In comparison, Addressables have a 20 KHz PWM rate, so even when moving the LED around, you won’t see the pixelation, the blending is very smooth. (we recommend Addressables if you can use them!)
This is a full meter of the 144 LED-per-meter version of our Addressable strips, on white flex PCB. We also have this in Warm White and RGB full color.
The strip is made of flexible PCB material, and comes with a weatherproof sheathing. You can cut this stuff pretty easily with wire cutters, there are cut-lines every 1 LED. Solder to the 0.1″ copper pads and you’re good to go. Of course, you can also connect strips together to make them longer, just watch how much current you need! We have a 5V 4A power supply that can drive a half meter or meter, a 5V/10A supply that can drive a couple meters (depending on use) You must use a 5V DC power supply to power these strips, do not use higher than 6V or you can destroy the entire strip
This strip comes as a single full meter with a 4-pin JST SM connector on each end. If you buy multiples, you will get multiple 1 meter strips, they will not come on a continuous strip! To wire up these strips we suggest picking up some JST SM plug and receptacle cables for the signal wires For the power wires, you will also probably want a 2.1mm DC jack to wire in so you can connect one of our 5V wall adapters to power it.
