    Adafruit 5050 RGB LED with Integrated Driver Chip - 10 Pack

    -Titulo Original : Adafruit 5050 RGB LED with Integrated Driver Chip - 10 Pack-Fabricante : ADAFRUIT-Descripcion Original: Adafruit Part Number: 1655 // Stock Type: NeoPixels >> NeoPixel LEDs // In Stock & Ready to Ship // Make your own smart LED arrangement with the same integrated LED that is used in our NeoPixel strip and pixels. This tiny 5050 (5mm x 5mm) RGB LED is fairly easy to solder and is the most compact way possible to integrate multiple bright LEDs to a design. The driver chip is inside the LED and has ~18mA constant current drive so the color will be very consistent even if the voltage varies, and no external choke resistors are required making your design minimal. Power the whole thing with 5VDC and you're ready to rock. This is the 4 pin LED chip version, not 6. It is code compatible and the same over-all shape and functionality but not the same pinout so you cannot use these to replace an 'S chip. If you are designing a new PCB we suggest going with the B, since it has built in polarity protection. Other than that, B and S are the same brightness, and use the exact same code interface. The LEDs are 'chainable' by connecting the output of one chip into the input of another - see the datasheet for diagrams and pinouts. To allow the entire chip to be integrated into a 6-pin package, there is a single data line with a very timing-specific protocol. Since the protocol is very sensitive to timing, it requires a real-time microconroller such as an AVR, Arduino, PIC, mbed, etc. It cannot be used with a Linux-based microcomputer or interpreted microcontroller such as the netduino or Basic Stamp. The LEDs basically have a WS2811 inside, but fixed at the 800KHz 'high speed' setting. Our wonderfully-written Neopixel library for Arduino supports these pixels! As it requires hand-tuned assembly it is only for AVR cores but others may have ported this chip driver code so please google around. An 8MHz or faster processor is required.These raw LEDs are cut from a reel and/or might be loose. They may not suitable for pick & place + reflow. We recommend these for careful hand soldering only!

    Adafruit LED Lighting Modules NeoPixel 1/4 60 Ring RGB LED W

    -Titulo Original : LED Lighting Modules NeoPixel 1/4 60 Ring RGB LED WS2812 (1 piece)-Fabricante : ADAFRUIT-Descripcion Original: Adafruit Part Number: 1768 // Stock Type: NeoPixels >> Rings // In Stock & Ready to Ship // The biggest NeoPixel Ring yet! With four of these you can make a huge ring with 60 ultra bright smart LED NeoPixels are arranged in a circle with a 6.2 diameter. Each order comes with just the quarter ring. Four of this item are required to make a large ring. You will have to solder them together as well, so for the full ring of 60 LEDs, buy four and solder them together! Also, you'll need to give these mechanical backing, the solder joints are only for electrical signal, not strong enough to hold it together The rings are 'chainable' - connect the output pin of one to the input pin of another. Use only one microcontroller pin to control as many as you can chain together! Each LED is addressable as the driver chip is inside the LED. Each one has ~18mA constant current drive so the color will be very consistent even if the voltage varies, and no external choke resistors are required making the design slim. Power the whole thing with 5VDC and you're ready to rock. There is a single data line with a very timing-specific protocol. Since the protocol is very sensitive to timing, it requires a real-time microcontroller such as an AVR, Arduino, PIC, mbed, etc. It cannot be used with a Linux-based microcomputer or interpreted microcontroller such as the netduino or Basic Stamp. Our wonderfully-written Neopixel library for Arduino supports these pixels! As it requires hand-tuned assembly it is only for AVR cores but others may have ported this chip driver code so please google around. An 8MHz or faster processor is required. Comes with one quarter ring of 15 x individually addressable RGB LEDs assembled and tested. We recommend you buy four to build the full circle as this is just the 1/4 of the circle...
