A 100-pack of individual NeoPixel RGB 5050 LEDs with integrated WS2812B-compatible driver chips. Each 5mm × 5mm LED includes ~18mA constant-current drive per channel, so colour remains consistent regardless of voltage variation — no external resistors needed. Power with 5VDC.
These are the 4-pin (WS2812B) variant with built-in reverse polarity protection. They are chainable — connect the data output of one LED to the data input of the next. Requires a real-time microcontroller (AVR, Arduino, PIC, etc.) running at 8MHz or faster. Not compatible with interpreted controllers or Linux-based microcomputers for direct driving.
Key Features
- Integrated Driver – WS2812B-compatible, 800KHz protocol
- Constant Current – ~18mA per channel, no external resistors needed
- 4-Pin Package – Built-in reverse polarity protection (B variant)
- Chainable – Single data line, daisy-chain multiple LEDs
- 24-bit Colour – 8-bit PWM per R/G/B channel

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.
- PWM
- Pulse Width Modulation is a way for a digital pin to simulate variable output power by switching on and off very quickly. It matters for controlling things like LED brightness, motor speed, or servo-style signals from a microcontroller pin.
- reverse polarity protection
- A circuit feature that helps protect the board if power is connected the wrong way around. It matters because it can reduce the chance of damaging the breakout during wiring mistakes, especially in classroom or prototyping use.
- 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.
