Lincoiah SPI signal amplifier is compatible with all kinds of 5V-TTL signal. It receives one signal and simultaneously output 4 or 8 channels of signals. Each channel can control the same quantity of LED pixels as main controller.It can outputs 8 channels for addressable LED strips with single data wire, such as WS2812B, WS2811, SK6812, SK6812-RGBW,SM16703, etcIt can outputs 4 channels for addressable LED strips with data & clock wires or dual data wires, such as WS2813, WS2815, CS8812, AL2815, WS2801, APA102, SK9822,etcDC5V~24V wide range of working voltage, but it cannot regulate the output voltage. That means the output voltage of power supply must be the same as the work voltage of your led lights.Multiple signal amplifiers can be cascaded together synchronously. Particularly suitable for small and medium dream color lighting projects.Working voltage: DC 5V~24VWorking temperature: -20-60COutput: 8 channels / 4 channelsCompatibale IC type: WS2812B,WS2811,SK6812, SK6812-RGBW,SM16703,WS2813, WS2815, CS8812, AL2815, WS2801, APA102, SK9822,UCS1903, LPD6803, LPD8806, APA102Size: 140mm x 75mm x 26mmColour:As shownMaterial:MetalPackage Contents:2 x SP901E Signal AmplifierOnly the above package content, other products are not included.Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing.
