It strengthens and regenerates the SPI control signal between the LED controller and addressable LED products, helping improve signal stability in suitable installations.
C-SPI Addressable LED Signal Amplifier
C-SPI Addressable LED Signal Amplifier
The C-SPI Amplifier is designed to strengthen and regenerate the digital control signal between an addressable LED controller and compatible SPI LED strips, modules or light bars.
Separate versions are available for single-data-line and two-wire data-plus-clock signals. The amplifier receives its own DC power input and only processes the control signal—it does not provide operating power to the connected LED strip or LED fixture.

FAQ
No. The amplifier only processes the digital signal. The LED strip or LED fixture requires a separate correctly sized power supply.
Choose the version according to the LED IC protocol:
Single-line version for DAT and GND signals
Two-wire version for DAT, CLK and GND signals
The LED controller and LED product must use the same signal protocol.
Yes. Versions are available for DC 5V, 12V and 24V systems. The amplifier voltage should match the project power configuration.
