Transform your creative lighting projects with a kit designed to wow at first glow . This next‑generation 1mm COB LED Driver Kit brings together ultra‑flexible 360° COB filaments , a smart 7‑channel hybrid output , and rock‑solid power management —all in one compact board built for makers who refuse to settle for ordinary . Whether you're crafting wearable light art , cinematic ambient effects , model accents , or custom prototypes , this kit delivers brilliant cool‑white illumination , buttery‑smooth dimming , and multiple strip configurations that unlock a whole new level of creative freedom . If you want lighting that’s sleek, stable, and stunning, this is the kit that makes your ideas shine brighter than ever . Features Power Supply When driving all channels simultaneously, the total current may exceed the limit of a standard computer USB port, which may cause flickering or dimming. In this case, please connect a 3.7V Li-Po battery or use a 5V/2A USB wall adapter for stable operation. Adapted for 1mm 3V COB LED Strips This kit includes 5 different types of flexible COB LED strips (1mm width) designed for various project needs. The onboard hardware current limiting is precisely tuned for 3V COB strips, ensuring safe and stable performance. Strategic 7-Channel Hybrid Output The board integrates 3 High-Power Channels (300mA) for bright illumination and 4 Low-Power Dimmable Channels (80mA) for breathing, fading, or ambient effects. One board manages both strong lighting and dynamic effects. 1mm Ultra-Flexible & 360° Cool White The included filaments are made from flexible FPC and silicone phosphor, featuring an ultra-narrow 1mm width and providing a 360° full-angle glow. They output 6500K Cool White with CRI >80, offering smooth, dot-free, continuous lighting far superior to rigid LEDs. Versatile Single & Double-Ended Designs The kit supports both Single-Ended and Double-Ended COB strip structures. Single-ended strips allow clean wiring in tight spaces, while double-ended strips ensure uniform voltage distribution and consistent brightness across the entire strip.
