Note: It is not a controller . It works with controller together. Can not support 4 pin or 5 pin RGB/RGBW no IC chip 5050 LED strip . This SPI is compatible with all kinds of 5V-TTL signal dual signals. 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 output 8 channels for addressable LED strip with single data wire, such as WS2812B, WS2811, SK6812RGB, SK6812-RGBW,SM16703, etc. It can output 4 channels for addressable LED strip with data & clock wires WS2801, APA102, SK9822 or dual data wires, such as WS2813, WS2815 You can use one controller to control DC5V WS2812B and DC5V WS2813 LED strip at the same time, control DC12V WS2811 ,DC12V WS2815, DC12V 1903, DC12V 6803 at the same time via this singal amplifier since they have the same singal. DC5V~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. The current through the amplifier is limited, when the current consumed is high, you need to add the power supply of the corresponding voltage. Multiple s can be cascaded together synchronously. Particularly suitable for small and medium dream color lighting projects. It can work with K-1000C, SP105E, SP108E, SP107E, CSY08, CSY07, Raspberry pi, for Arduino X2 music controller.<br><br>Working voltage: DC5V~24V Working temperature: -20-60Celsius Output:8 channels / 4 channels Compatibale IC type: WS2812B,WS2811,SK6812, SK6812-RGBW,SM16703,WS2813, WS2815, CS8812, AL2815, WS2801, APA102,SK9822,UCS1903, LPD6803, LPD8806, APA102 Static power consumption: Less than 1W Colour:black Material:metal Size: 140mmx56mmx28mm Weight:240g<br><br>Package Contents: 1 x SP901E Precautions:The controller cannot regulate the output voltage at the VCC.
