Expand One SPI Signal into 4 or 8 Synchronized Outputs
The MALIIGAZA Mini SPI Signal Amplifier receives one 5V-TTL control signal and simultaneously repeats it to 4 or 8 output channels, making it easy to connect multiple addressable LED strips in parallel.
Designed for 3-pin programmable LED strip systems and compatible with common SPI ICs such as WS2811, WS2812, WS2812B, SK6812 and 16703.
One Controller Signal. Multiple LED Strip Branches.
When your SPI lighting project requires several addressable LED strips to run the same effects at the same time, connecting everything directly to one controller output may not be practical.
This compact SPI signal amplifier takes the signal from your main LED controller and distributes the same synchronized signal to 4 or 8 separate outputs.
Important Compatibility Notice
This product is an SPI signal amplifier, not an LED controller.
It must be used together with a compatible addressable LED controller.
For 3-pin SPI addressable LED strips only. It does NOT support standard 4-pin RGB or 5-pin RGBW / RGBCCT analog LED strips.
Key Benefits
1 Signal to 4 / 8 Outputs
Receive one SPI control signal and output the same synchronized signal through 4 or 8 channels.
5V-TTL Signal Compatible
Compatible with common 5V-TTL digital signals used by many programmable addressable LED controllers.
Synchronized LED Effects
All output channels repeat the same signal so multiple LED strip branches can display synchronized lighting effects.
Cascade Multiple Amplifiers
Multiple signal amplifiers can be cascaded when additional synchronized output branches are required.
Why Use an SPI Signal Amplifier?
Parallel Multi-Strip Signal Distribution
The amplifier makes it easier to divide one controller signal into several parallel LED strip branches while keeping the lighting effects synchronized.
Same Signal on Every Output
Each output repeats the same signal from the main controller. Each branch can follow the same programmed pixel sequence and lighting effect as the main controller output.
4-Port and 8-Port Versions
Choose the 4-output version for smaller projects or the 8-output version when more parallel LED strip branches are required.
Mini Size for Flexible Installation
The compact design is suitable for small and medium dream-color lighting projects where installation space is limited.
Compatible with Popular Addressable LED Controllers
The amplifier is designed to work with addressable programmable LED controllers using a compatible 5V-TTL SPI signal.
Compatible controller examples include:
Compatibility depends on the controller output signal, wiring and LED strip protocol.
Compatible Addressable LED ICs
It can also be used with other compatible addressable LED systems that use the appropriate 5V-TTL SPI control signal.
Cascade Multiple Amplifiers for More Outputs
Need more than 4 or 8 parallel LED strip branches? Multiple amplifiers can be cascaded together to expand the number of synchronized signal outputs.
This makes the amplifier especially useful for small and medium addressable RGB, RGBIC and dream-color lighting projects with repeated or symmetrical LED layouts.
Ideal Applications
Run several LED strip branches from the same controller signal.
Create synchronized programmable lighting across multiple installation areas.
Suitable for Arduino, Raspberry Pi and ESP8266 based addressable LED projects.
Useful for rooms, cabinets, displays and decorative smart lighting installations.

Basic Connection Guide
- Turn off the power before wiring.
- Connect the compatible SPI LED controller signal to the amplifier input.
- Connect the required addressable LED strip branches to the amplifier outputs.
- Check voltage, data signal and ground wiring before powering the system.
- Turn on the controller and confirm that all connected branches display the synchronized effect correctly.
Troubleshooting
LED strips do not respond
Confirm that a compatible SPI controller is connected. The amplifier cannot generate control effects by itself.
Some outputs are not working correctly
Check data, power and ground connections and confirm that the LED strips use a compatible addressable protocol.
LED effects are incorrect
Check the IC type, color sequence and pixel settings in the main SPI controller.
4-pin or 5-pin LED strip does not work
This amplifier is designed for compatible 3-pin SPI addressable LED strips. Standard 4-pin and 5-pin analog LED strips are not supported.
Important Notes
1. This product is a signal amplifier, not a controller.
2. A compatible SPI addressable LED controller is required.
3. Designed for compatible 3-pin SPI LED strips only.
4. Standard 4-pin RGB and 5-pin RGBW / RGBCCT analog LED strips are not supported.
5. The amplifier repeats the controller signal. It does not independently create colors, effects, animations or app control functions.
6. Always confirm controller signal type, LED strip protocol, voltage and wiring before connection.
Frequently Asked Questions
