4-Channel SPI Signal Amplification: Expands the output power of your SPI controller and accommodates more LED strips or pixel segments.
Signal Regeneration & Stabilization: Repeats and strengthens SPI data signals to prevent flicker, delayed response, or color distortion on long cable runs.
Wide Compatibility With Pixel ICs: Supports common SPI chips including WS2811, WS2812, WS2813, UCS1903, SM16703, and other standard addressable LED protocols.
High Output Capacity: Can drive additional LED pixels beyond controller limits, ideal for large-scale installations.
Synchronization of Effects: Ensures smooth, uniform color transitions and animation effects across all connected strips.
Robust Build & Safety: Features MOSFET output, short-circuit protection, and stable heat management for long-term reliability.
Easy Terminal Wiring: Screw-type connectors make installation simple for both professionals and DIY users.
