2.4Ghz Switching Value Wireless Transceiver Modules 6-channel
Product Description
2.4Ghz Switching Value Wireless Transceiver Modules (OW3621 SoC Based)
Brief Introduction
The DL-OW3621-SW Wireless Module is an ultra-low-power 2.4GHz RF SoC-based multi-channel switching value module developed by DreamLNK. This module integrates digital switching value (DI/DO) acquisition and control with full-duplex serial port transparent transmission. It eliminates the need for
complex underlying driver software design, pre-defined communication protocols, or key value configurations. With optimized features such as code matching, remote control, low power consumption, and co-frequency interference resistance, the DL-OW3621-SW is ready to use out of the box. When used in a product, the customer only needs to externally connect necessary input buttons, output loads, a pairing button, a pairing indicator, etc. The module can be used without any programming.
The RF module only requires a 3.3V power supply, a transmit button, LED transmit and pairing status indicators. The corresponding output ports of the receiving module can directly output level signals. The standard module features 6 independent control signals: the 6 buttons on the transmitter side correspond to the 6 signal outputs of the receiver. It supports single-channel remote control as well as simultaneous multi-channel remote control.
The module is small in size, low in power consumption, and easy to use. The transmitter module only needs a button board designed according to the remote-control housing; the receiver module requires no external components. The I/O port signals can directly drive small loads such as LEDs, motors, relays, etc., or the 6 output signals can be used as parallel level signals to the I/O port of the MCU for use. It is very convenient and simple to use.
