The SP901E digital LED signal amplifier is a professional SPI signal distribution unit designed to expand and stabilise control signals for addressable (pixel) LED strip installations. It receives a single SPI signal and simultaneously outputs 4 or 8 identical signal channels, allowing multiple LED runs to be driven in perfect synchronisation.

Each output channel can control the same number of LED pixels as the main controller, making the SP901E ideal for projects where long runs, multiple directions, or complex layouts would otherwise suffer from signal degradation. Multiple amplifiers can also be cascaded together for larger installations while maintaining accurate timing and colour consistency.

The SP901E supports a wide range of single-data, dual-data, and data + clock SPI LED chipsets, making it a highly flexible solution for commercial LED specialists working on architectural, decorative, and “dream colour” lighting projects. It is particularly well suited to small and medium-scale installations where reliable signal replication is critical.

LED Chipset Compatibility

8-Channel Output (Single Data Wire SPI):

• WS2812B
• WS2811
• SK6812 RGB
• SK6812 RGBW
• SM16703

4-Channel Output (Data + Clock or Dual-Data SPI):

• WS2801
• APA102
• SK9822
• WS2813
• WS2815

The amplifier allows mixed voltage SPI systems to be controlled simultaneously, for example:

• DC5V WS2812B and WS2813
• DC12V WS2811, WS2815, 1903, 6803

As long as the signal type is the same, the SP901E will distribute it correctly.

Power & Installation Notes

• Supports a wide working voltage range from DC 5V to 24V
• Does not regulate voltage. Output voltage must match the LED strip voltage
• When total current demand is high, additional power supplies must be added
• Designed for signal amplification only, not power amplification
