Seeed Studio COB LED Driver Board 💡 is a 7-channel COB LED driver dock designed for Seeed Studio XIAO. This COB LED Driver Board expands the XIAO Development Board GPIO power limits and offers 7 output channels specifically tailored for driving low-power, ultra-narrow 1mm 3V COB LED strips ✨. With integrated PMIC battery management 🔋, the Seeed Studio COB LED Driver Board for XIAO is a plug-and-play solution for compact, high-brightness wireless lighting setups. It’s the ideal COB LED Driver Board for creators using Seeed Studio XIAO.
Note:
⚠️ Power Supply: When driving all channels simultaneously, total current may exceed a standard computer USB port (causing flickering or dimming). Please connect a 3.7V Li-Po battery or use a 5V/2A USB wall adapter for full COB LED brightness and stable output.
🔧Feature
- Adapted for 1mm-wide 3V COB LED Strips : Onboard hardware current limiting is tuned for flexible 3V 1mm COB LED strips. Tiered 300mA and 80mA current limits effectively drive different COB LED lengths, delivering a safe, stable, plug-and-play experience for Seeed Studio XIAO users who need a reliable COB LED Driver Board 💡.
- Strategic 7-Channel Hybrid Output : Manage your lighting with one board: 3 High-Power Channels (300mA) for bright main COB LED lighting and 4 Dimmable Channels (80mA) for breathing/fading effects via XIAO PWM. Keep main lights bright and effects dynamic — a perfect match for Seeed Studio ecosystems.
- Battery Management for Wireless Projects : Integrated PMIC power supports 3.7V Li-Po batteries 🔋 or high-power 5V USB adapters. Ideal for wireless installations and high-brightness desktop ambient COB LED lighting with Seeed Studio XIAO.
- Easy Sensor Expansion : Includes a standard Grove I2C connector 🧩 for hassle-free sensors. Build reactive COB LED projects that respond to the environment — seamlessly with Seeed Studio and XIAO.
