You can set the color of each LED's red, green and blue component with 8-bit PWM precision (so 24-bit color per pixel). There are 60 RGB LEDs per meter, and you can control each LED individually! Yes, that's right, this is the digitally-addressable type of LED strip. These LED strips are even more fun and glowy. If you want to drive the entire strip and have some other libraries included, use a Mega.

Third, just because you have all those pixels doesn't mean you have the RAM for it - the entire strip must be buffered in memory, and we've found many Arduino UNO projects only have about 1500 bytes of RAM available after all the extras are included - enough for about 500 LED pixels.

We have example code for using with the Arduino Uno/Mega microcontroller at 8MHz and 16MHz, and with a little effort you can use with the Raspberry Pi, or Beagle Bone Black, but it will not work with the Basic Stamp, NETduino, any other interpreted/virtual machine microprocessor or any processor slower than 8 MHz. The protocol used is very very timing-specific and can only be controlled by microcontrollers with highly repeatable 100nS timing precision. Second, to get high density, the controller chip is inside the LED, which is kind of cool, but also means that the chip only uses a single pin for input and a single pin for output.A good power supply such as our 5V 10A supply is key! The max rating is assuming all the LEDs are on full white, usually the actual current for colorful design is about 1/3 to 1/2 the max current. First up, the higher density means much higher power usage over a certain distance - 18 Watts max (~3.5 Amps 5V) per meter instead of 9.6 Watts max (~2 Amps 5V).

This is the strip with white flex PCB, its identical to the black 60 LED/meter except it has a different color mask on the flex stripĪll your dreams answered, yet there are a few things to watch for. You wanted less noticeable strip color - this strip has white-colored flex PCB, which will be less visible against white-painted walls. You wanted thinner strips? Now only 12.5 mm wide, 10 mm if you remove the strip from the casing. You thought it couldn't get better than our world-famous 32-LED-per-meter Digital LED strip but we will prove you wrong! You wanted twice the LEDs? We got it (well, its 1.875 times as many but that's within a margin of error).
