BTF-LIGHTING SP901E 8-Channel SPI Signal Amplifier for WS2812B/WS2811 and More | RGB LED Strip & Dream Color Matrix Panel

Overview

The BTF-LIGHTING SP901E is a compact, multi-channel signal amplifier designed to work with a controller. It extends a single data signal into 4 or 8 output channels, enabling synchronized lighting across a variety of addressable LED strips and matrix panels. With a versatile voltage range and wide IC compatibility, it supports flexible, scalable RGB and dream color setups without taking over the light control.

Versatility and Compatibility

Designed to cooperate with a broad ecosystem of LEDs and controllers, the SP901E can output 8 channels for data-only strips and 4 channels for data-and-clock setups. It supports common ICs such as WS2812B, WS2811, SK6812, SK6812-RGBW, SM16703, WS2813, WS2815, and more, including CS8812, AL2815, WS2801, APA102, SK9822, UCS1903, LPD6803, and LPD8806. This broad compatibility means you can mix different LED types on a single project under the same signal line, depending on your layout and power constraints.

• Output options: 8 channels for single-data-wire strips; 4 channels for dual-data-wire strips.
• Cross-compatibility with 5V-TTL signal controllers and multiple LED families.

How It Works

Note that the SP901E is not a controller itself. It works alongside a controller to fan out signals. The device accepts a signal and reproduces it across multiple channels, helping you expand your lighting system without replacing your main controller.

• You can drive 5V WS2812B and 5V WS2813 strips from the same main controller via this amplifier.
• It supports wide working voltages from 5V to 24V, but it does not regulate the output voltage.

Installation Tips

For reliable operation, ensure the power supply voltage matches the LED load. If the current draw increases, add an appropriate power supply for that voltage. Multiple SP901E units can be cascaded to synchronize larger projects, making it suitable for dream color lighting setups and light displays.

• Cascading allows synchronized effects across larger installations.
• Works with common controllers and microcontrollers like Raspberry Pi or Arduino-based systems.
