The SPI is compatible with various 5V- signal dual signals. It receives a signal and outputs 8 signals at the same time. Each channel can control the same number of LED pixels as the main controller. You can use a controller to control both DC5V WS2812B and DC5V WS2813 LED strips at the same time. Through this SINGAL amplifier, you can control DC12V WS2811, DC12V WS2815, DC12V 1903, DC12V 6803 at the same time because they have the same SINGAL. DC5V-24V has a wide operating voltage range, but the output voltage cannot be adjusted. This means that the output voltage of the power supply must be the same as the operating voltage of the LED lamp. The current through the amplifier is limited, and when the current consumed is high, a corresponding power supply needs to be added. Multiple s can be cascaded together simultaneously, which is especially suitable for small and medium-sized dream color lighting projects. It can be used with K-1000C, SP105E, SP108E, SP107E, CSY08, CSY07, for , for X2 music controllers.<br><br>Type:8-channel magic lantern with amplifier Input voltage:DC5-24V 5V/12V/24V universal Support multiple ICs:WS811/WS2812B/WS2813/WS2815/SK6812 Output:5V TTL Consumption:Less than 1W Colour:Black Material:Aluminum Alloy Size:15.5CMx5.5CMx2CM<br><br>Package Contents: 1 * <br><br>Only the above package content, other products are not included.
