NeoPixel RGB 5050 LED with Integrated Driver Chip - 100 Pack 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! Comes in a package with 100 individual LEDs. We have a ready-to-go component for this in the Adafruit EAGLE library | 0/100 | |||
NeoPixel Cool White LED w/ Integrated Driver Chip - 10 Pack - ~6000K For those of us who are maybe a little tired of rainbows, we now have 'smart LEDs' in monochrome! Make your own smart Cool White LED arrangement with the same integrated LED driver that is used in our NeoPixel 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) This tiny 5050 (5mm x 5mm) SMD LED is fairly easy to solder and is the most compact way possible to integrate multiple bright LEDs to a design. If you want to prototype with these, we recommend our 5050-size LED breakout PCBs, solder them on for a breadboard-friendly package NeoPixel LEDs use 800 KHz protocol so specific timing is required. On NeoPixels, the PWM rate is 400 Hz, which works well but is noticable if the LED is moving. In comparison, DotStars 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 DotStars if you can use them!) NeoPixels are 5050-sized LEDs with an embedded microcontroller inside the LED. You can set the brightness of each of 3 individual cool white dies epoxied into the case. Each LED acts like a shift register, reading incoming data on the input pins, and then shifting the previous data out on the output pin. By sending a long string of data, you can control an infinite number of LEDs, just tack on more or disconnect unwanted LEDs at the end. The PWM is built into each LED-chip so once you set the brightness you can stop talking to the strip and it will continue to PWM all the LEDs for you. Comes in a package with 10 individual LEDs. We have a tutorial showing wiring, power usage calculations, example code for usage, etc. for NeoPixel Please check it out! Please note that the tutorial and code talk about RGB, but of course, this LED is just WWW, three individual white LEDs instead. | 10/10 |
