MiBOXER 4-Channel SPI Signal Amplifier & Long-Distance RS485 Receiver for Addressable LED Strips

At the remote end, the receiver reconstructs the original 4-channel SPI output, driving up to four LED data lines with perfect synchronization and zero frame loss. Compatible with popular SPI controllers including ESP32, WLED, and MiBOXER SPI series, it solves the distance limitations of TTL signaling in architectural, commercial, and decorative lighting projects. With wide 5–24V DC input, compact housing, and four independently buffered outputs, the SPI-PA+ ensures reliable, flicker-free performance for demanding pixel LED applications. Ideal for installations where the controller must be placed far from the LED fixtures, it delivers plug-and-play simplicity with industrial-grade stability.

• Long-Distance Transmission:​ Extends SPI signal control up to 100 meters​ via RS485 over standard Cat6a network cable, eliminating TTL distance limitations.

• 4-Channel Independent Buffering:​ Features four parallel, regenerated SPI/TTL outputs for driving multiple LED strips with synchronized timing and zero frame loss.

• Wide Voltage Compatibility:​ Supports DC 5–24V​ input, making it suitable for various addressable LED types including WS2811, WS2812B, SK6812, and more.

• Universal Controller Support:​ Fully compatible with mainstream SPI LED controllers such as ESP32, WLED, and MiBOXER SPI systems for seamless integration.

• Plug-and-Play Reliability:​ Compact design with industrial-grade signal integrity; no external power amplification needed for LEDs—pure signal regeneration for flicker-free performance.
