SPI Pixel Sync Master & Slave Extend Module.
SPI TTL signal wiring cable can not be very long. If you want to extend the distance from the SPI controller output to the pixel LED lights, the SPI Sync Master & Slave is the best solution. You can also have multiple Sync Slaves wired in cascade to play in sync, with long distance (max 200m).
