What is SPI signal amplifier?
In addressable LED strip lighting applications, the use of SPI TTL amplifiers simplifies complex wiring problems. In order to reduce the pixel LED voltage drop, it is usually necessary to supply power at both ends to ensure the color consistency of the light strip.
As the digital led strip running distance increases, the SPI digital control signal will be weakened, resulting in a poor light effect at the end. Adding a LED signal amplifier is the best option for large-scale dream color lighting projects, avoid problems such as light flickering, lights being lit with a delay, etc.
