Hey there! These are super - cute Mini NeoPixel RGB LEDs! You can create your own smart LED setup using the same integrated LED found in our NeoPixel strips and pixels. These MINI RGB LEDs measure just 3.5mm x 3.5mm, which is half the size of the common 5x5mm NeoPixels. They're a breeze to solder and are the most space - efficient way to add multiple bright LEDs to your design. The built - in driver chip has a constant current drive, ensuring consistent color even when the voltage fluctuates. You don't need external choke resistors, keeping your design simple. Just power them with 5VDC and you're all set. This pack contains 10 NeoPixel Mini RGB LEDs with a white casing, and we also have black - cased ones. The LEDs are chainable. Connect the output of one chip to the input of another (check the datasheet for diagrams and pinouts). They use a single data line with a timing - specific protocol, so you'll need a real - time microcontroller like an AVR, Arduino, PIC, or mbed. Our well - written Neopixel library for Arduino supports these pixels. An 8MHz or faster processor is required. These LEDs are cut from a reel and might be loose, so they're not suitable for pick & place + reflow. Due to their sensitivity to moisture and temperature, we recommend careful hand - soldering only. They come in a package of 10 individual LEDs, and we have a ready - to - use component in the Adafruit EAGLE library.
Using these Mini NeoPixel RGB LEDs is easy. First, power them with 5VDC. To create a chain of LEDs, connect the output of one chip to the input of the next one. Refer to the datasheet for the correct diagrams and pinouts. You'll need a real - time microcontroller such as an AVR, Arduino, PIC, or mbed to make them work. An 8MHz or faster processor is required. When it comes to soldering, these LEDs are fairly easy to handle, but because they're cut from a reel and might be loose, we suggest hand - soldering them carefully. Avoid using them in pick & place + reflow processes as they're very sensitive to moisture and temperature. As for maintenance, keep them in a dry and cool place. If you're using our Neopixel library for Arduino, it'll make things even easier for you. Just make sure to check if other users have ported the chip driver code if you're using a different setup.
