This SPI signal booster is compatible with two different types of signal inputs, TTL and RS485. It receives signals and supports the output of 2 channels. Each channel can control the same number of LED pixels as the host controller.
Multiple signal amplifiers can be cascaded synchronously with each other. Especially suitable for small and medium dream colour lighting projects. It can work with K-1000C, SP105E, SP608E, SP107E, SP611E, SP630E, Raspberry pi, Arduino etc. controllers.
It can output 2 channels for addressable LED strips with a data line, such as WS2812B, WS2811, SK6812RGB, SK6812-RGBW, WS2813, WS2815 and other addressible LED strips. You can use the controller to control DC12V WS2811 SMD, DC12V WS2815 at the same time because they have the same signal.
DC5V~24V wide range of working voltage, but it cannot regulate the output voltage. This means that the output voltage of the power supply must be the same as the working voltage of the LED lights. The current through the amplifier is limited, if the consumed current is high, you need to add the power supply to the appropriate voltage.
Can be used alone or in cascade with multiple devices. When cascading with multiple devices, the differential RS485 signal is used for cascading between amplifiers to achieve signal transmission over long distances.

* Warm Tips * -- To ensure reliable switching, the transmission power of the front-end device must reserve a margin of at least 3 dB, i.e. the minimum transmission power of the front-end device must not be less than 1 dBm, otherwise this may cause instability of the receive/send switch.
* Performance* -- Built-in intelligent receive/transmit differentiation circuit, does not require front-end equipment to provide receive/transmit switch control signals. The transmission gain is manually adjustable, which is convenient for compatible wireless devices with different transmission power.
* Operation mode* -- This wireless range extension module works by default in the received state and amplifies the received signal. When it is detected that the front-end device is sending external signals, it immediately switches to the transmission and amplification state. The transmission gain is manually adjustable, which is convenient for compatible wireless devices with different transmission power.
* Maximum transmit power* -- 31.5 dBm (1.4 W) at 3.7 V supply voltage; 33.5 dBm (2.3 W) at 5.0 V supply voltage; 34.5 dBm (2.8 W) at 6.0 V supply voltage
* Applicable frequency band * -- Two-way signal power amplifier modules of the AB-IOT-433 / AB-IOT-510 / AB-IOT-868 series are suitable for various applications in the frequency bands 433MHz (420MHz-480MHz), 510MHz (470MHz-520MHz) and 868MHz (Europe Europe Europe 863MHz-870MHz). Its compact size and convenient use facilitate the development of products for high performance and remote applications in this frequency band.
