LED Driver Board for Seeed XIAO

The LED Driver Board for XIAO supports 5V and 12V addressable RGB strips, including WS2812, WS2813, and WS2815. Compatible with all XIAO boards, it works with WLED and Home Assistant for smart lighting control and includes built-in protection for reliable operation.

This LED driver board is a compact yet powerful solution supporting both 5V and 12V LED strips, including popular addressable RGB LEDs such as NeoPixel WS2812, WS2813, WS2815. Compatible with all XIAO boards, it enables smart control and automation through WLED and Home Assistant when using XIAO ESP32 Series, while offering flexible power options and comprehensive protection for safe, reliable operation in your lighting setup. XIAO is not included, but we offer a range of options here. This expansion board is currently not directly compatible with the XIAO nRF54L15 series because Arduino is not supported. However, the hardware interface is fully compatible, and developers can manually adapt the software if needed. Official software support from Seeed Studio is under development — stay tuned for updates!
