Product Details
✓Please notes：1. It is not advisable to exceed the current capacity of the signal amplifier. It is recommended to supplement the current on each LED strip to avoid overloading the signal amplifier and causing it to overheat. 2. This is a signal amplifier, not a controller. It requires a controller to provide the signal. It should works with controller together.
✓Work with all the addressble programmable LED strip controller, like DR03W DR04W DR05W SP630E SP530E SP105E SP107E SP608E SP602E Arduino R3 ,Rasp Pi , ESP8266 ,K-1000C etc．
✓Multiple signal amplifiers can be cascaded together synchronously. Particularly suitable for small and medium dream color lighting projects.
✓Can not support 3 pin, 5 pin or 6 pin FCOB SMD PMW SPI LED strip . This SPI signal amplifier is compatible with all kinds of 5V-TTL signal. It receives one signal and simultaneously output 4 outputs signals. Each output connector can control the same quantity of LED pixels as main controller.4 output connectors are the same lighting effect.
✓Support LED Strip Lights: 4pin SMD WS2815 WS2805 WS2813 TM1934 etc IC Chip SPI LED Strip, LED Bulb, Low voltage LED project, LED panel light,LED module,LED string．
