Adafruit NeoPixel Digital RGB LED Strip - White 30 LED - 1m [並行輸入品]

商品説明

1m 30 LED NeoPixel Digital RGB LED Strip (white backing)

These NeoPixel strips have 30 digitally-addressable pixel LEDs per meter and are very affordable and are only 12.5 mm wide, 10 mm if you remove the strip from the casing. This is the strip with white flex PCB.

There are some things to watch for:

• These LED's use about 9.5 Watts max (~2 Amps @ 5V) per meter.
• 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)
• A good power supply would be 5V @ 2A (2000 mA) or 10A max. supply is key!

To make the strip thin and easier to manufacture, 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. The protocol used is very timing-specific and can only be controlled by microcontrollers with highly repeatable 100nS timing precision. Look for example code at Adafruit or Jameco Electronics for using with the Arduino Uno/Mega microcontroller at 8MHz and 16MHz, but it will not work with the Raspberry Pi, Basic Stamp, NETduino, any other interpreted/virtual machine microprocessor or any processor slower than 8 MHz.

The way the pixels are controlled by an Arduino, the entire strip must be buffered in memory, and we've found many Arduino UNO projects only have about 1500bytes of RAM available after all the extras are included - enough for about 500 LED pixels. If you want to drive the entire strip and have some other libraries included, you may need to use a Mega.
