SP901E Spi Signal amplifier TTL splitter repeater adressable led pixel SP901E SPI Signal Amplifier for WS2812B WS2811 WS2813 Pixel RGB LED Strip Signal Repeater Addressable Dream Color Tape DC 5V-12V SP901E 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, etc It 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,etc 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. Multiple signal amplifiers can be cascaded together synchronously. Particularly suitable for small and medium dream color lighting projects. Parameter Working voltage: DC 5V~24V Working temperature: -20-60C 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 Size: 140mm x 75mm x 26mm Precautions (1) The controller cannot regulate the output voltage at the VCC. That means the output voltage of your power supply must be the same as the work voltage of your led lights. If your lights need 5V input, please use a 5V power supply, never use 12V or 24V power supply. (2) The current through the amplifier is limited ,when the consumption current is huge, customer need to increase power supply additionally.
