Designed for COB Lighting Creativity
This driver dock breaks through the GPIO power limitations of small MCUs, offering 7 independent high-current output channels to drive compact COB LED strips with ease. Simply slot in any Seeed Studio XIAO board——and instantly transform it into a highly capable lighting controller.
Because it supports ultra-narrow 1mm 3V COB LED strips, the board is ideal for creating light effects in confined spaces where traditional LED strip solutions won’t fit.
Why COB LED Strips?
🌟 Seamless, Dot-Free Light: Unlike SMD strips that show individual LED beads, COB strips pack many LED chips tightly on the substrate. This produces: Completely continuous illumination & Zero visible “LED dots” & Softer, smoother, and more premium lighting. Ideal for cameras, décor, displays, and architectural lighting.
💡 Higher Efficiency & Brightness: The dense chip arrangement and improved thermal dissipation mean: Higher luminous efficiency & Stronger brightness at the same power level & Longer lifespan under continuous use
🌀 Flexible and Easy to Install: COB strips offer excellent bending radius, making them suitable for: Hidden cove lighting & Shelf and cabinet lighting & Wearables and props & Creative shapes and tight installations
🎨 Uniform, Spot-Free Illumination: Perfect for any application needing smooth, uninterrupted glow: Mood lighting & Backlighting & Under-cabinet illumination & Accent and edge lighting. Combined with the 7-channel driver dock, you can craft intricate multi-zone effects that stay clean and uniform.
✂️ Customizable Length with Single-Side Electrodes: COB strips feature single-side positive/negative electrodes, allowing you to cut them to the desired length and connect directly to the driver dock. This makes installation flexible and convenient for spaces of varying size without affecting performance.
Choose from COB strips in different lengths with versatile connection options, all powered easily with a battery-driven, wire-free board. Perfect for adding soft, seamless light to your desk, bedside, shelves, or any creative corner—cut, connect, and place wherever you like for a cozy, glowing touch.

🎄 Christmas Lighting
Ultra-narrow COB strips outline windows, wrap around the Christmas tree, or hang vertically like falling lights. Battery-powered and XIAO-controlled, they can create soft breathing effects that mimic the flicker of a fireplace, highlighting ornaments with smooth, uninterrupted illumination—no visible LED dots, just warm, cozy holiday glow.
🏠 Smart Home Ambience
Integrate the driver board into cabinets, shelves, stairways, or hidden lighting coves to create clean, uniform ambient light. With the Grove sensor port, you can add motion sensors and light sensors to build responsive lighting—hallway lights that turn on only when someone passes by, under-cabinet illumination that automatically adjusts brightness based on ambient light, or mood lighting that adapts throughout the day. And when paired with Home Assistant, these behaviors become fully customizable: trigger lights with a PIR motion sensor, dim or brighten them using real-time illuminance readings, or link them with other smart-home devices to create seamless, energy-efficient automations tailored to your needs.
