2.4G Wireless Switch Control RF Module with SOC Design

DL-BK24K6 TX/RX wireless switch control module is a 2.4G SOC multi-channel switch output module developed by DreamLNK. Customers do not need to design complex underlying driver software, also no need to define the transceiver communication protocol, nor the key value definition. We have internally designed 2.4G code matching, remote control, low power consumption, and Co-Channel Interference optimization. You just need to connect the necessary input buttons and output loads, code matching buttons, code matching indicators, etc. It can be used without any programming. 

For the entire DL-BK24K6 series module: TX is a RF transmit module, RX is a RF receive module. While 52TX is also a transmit module, but with optimized power consumption (developed specifically for battery-powered systems), which only requires a 3.3V power supply, transmitting buttons, LED transmitting and code status indication; the output port corresponding to the receive module can output level signals. The standard module has 6 independent control signals. The 6 buttons on the transmitting end correspond to the 6 signal outputs of the receive module. It can realize single-channel remote control, and can also realize multi-channel remote control.

These RF modules are compact in size, low in power consumption, and easy to use. The transmit module only needs to design the key board according to the remote control shell. The receive module has no peripheral parts. The signal of the IO port can directly drive small loads such as LEDs, motors, and relays. The channel output signal is provided to the IO port of the MCU as a parallel level signal. It is very convenient and simple to use. Multiple sets of products can be used at the same time without interfering with each other, effectively solving the interfering problem at the same frequency, especially 315 / 433M remote control products transmitting at the same time.

Customized description: The module adopts 6-channel switching value as a standard, which can meet the requirements of 1-6 signal remote controls. If more signal control is required, the number of buttons of the transmit module can be expanded by scanning the matrix, or add more I/O, to increase the number of signal channels of the receive module; you can also adjust the power, rate, and data format of the transmitter to reduce power consumption according to product application requirements. For specific design and development requirements, please contact our RD department.
