Itsy Bitsy Teenie Weenie Mini NeoPixel RGB LEDinis! Make your own smart LED arrangement with the same integrated LED that is used in our NeoPixel strip and pixels.
These MINI (3.5mm x 3.5mm) RGB LEDs are fairly easy to solder and are half the size of the standard 5x5mm NeoPixels you may be used to seeing. You can see our comparison photo above. They're the most compact way possible to integrate multiple bright LEDs to a design. The driver chip is inside the LED and has a constant current drive so the color will be very consistent even if the voltage varies, and no external choke resistors
This is the Pack of 10 NeoPixel Mini RGB LEDs with a Black Casing. We also have minis in a White Casting here.
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 4-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 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. 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. LEDs are notoriously difficult to use in an automated process due to being very sensitive to moisture and temperature. We recommend these for careful hand soldering only! Comes in a package with 10 individual LEDs. We have a ready-to-go component for this in the Adafruit EAGLE library
Jargon buster
Plain-language definitions for the technical terms used above.
- AVR
- AVR is a family of 8-bit microcontrollers used in many classic Arduino-style boards. If a USB host library mentions AVR support, it suggests the examples or compatibility may be aimed at those older microcontroller boards.
- LED
- A light-emitting diode is a small electronic component that lights up when current flows through it in the correct direction. In this kit, LEDs create the flashing effect, so polarity and correct soldering matter for the project to work.
- microcontroller
- A microcontroller is a small computer on a chip that runs your program and controls connected inputs and outputs. For this product, it is the part that reads buttons and sensors, drives the display and speaker, and communicates over Bluetooth.
- NeoPixel
- A type of addressable LED system where colour data is sent along a single digital data line from one LED or controller to the next. Compatibility matters because the timing and signal format must match for the lights or driver board to respond correctly.
- RGB
- Short for red, green and blue, usually referring to an LED that can mix those three colours. It matters because controlling an RGB LED teaches how separate outputs combine to create different colours.
