Adafruit NeoPixel 332 LED-per-Meter Silicone Bead LED Strip - 0.5 Meter
Best high-density lighting for makers creating smooth, professional-grade custom animations.
Illuminate your projects with the Adafruit NeoPixel 332 LED-per-Meter Silicone Bead LED Strip. This 0.5-meter strip boasts an ultra-high density of 332 miniature NeoPixels per meter, offering smooth and continuous color gradients thanks to its milky silicone bead coating. Each LED is individually addressable, allowing for precise control over red, green, and blue components for 24-bit color. The flexible PCB strip is housed in weatherproof sheathing and features a JST SM 3-pin plug and socket for easy connection. It requires a 3-5V DC power supply and is compatible with Arduino, MakeCode, and CircuitPython.

What customers say
Users consistently celebrate this LED strip for its exceptional light quality, noting the high density effectively eliminates the dot matrix effect. The integrated diffusion layer creates a smooth, continuous line of vibrant light, perfect for professional installations where uniformity is key. Reliability and seamless library integration are frequently praised aspects of the Adafruit ecosystem. The primary consideration is the premium cost, which users often accept given the superior performance. A crucial operational point is the significant power requirement due to the high LED count, demanding careful power supply planning for optimal results. This product is viewed as the benchmark for high-fidelity, dotless LED lighting.
Know before you buy
Yes, the strip is designed to be cut to your desired length. Be sure to follow the designated cut marks on the PCB to ensure the remaining segments continue to function correctly.
You need a 5V DC power supply capable of handling the high current draw. At full brightness with all white LEDs, this 0.5-meter strip can draw up to 10A, so ensure your power source is adequately rated.
Yes, the strip is housed in a weatherproof silicone bead coating, making it durable enough for outdoor environments. However, ensure your power connections are also protected from moisture.
These LEDs are compatible with most microcontrollers that support the NeoPixel protocol, including Arduino, CircuitPython, and MakeCode platforms. You only need a single digital pin to control the entire strip.
The milky silicone bead acts as a diffuser, which softens the individual LED points. This creates a smooth, continuous glow rather than distinct, harsh dots of light.
