RS485 wireless module 35 rail mounting block integrated circuit 433 470MHZ
WLK-485 Is a highly integrated long-distance half-duplex micro-power wireless data transmission module, the maximum output power can reach +20 DBm, which to some extent to meet the RF signal amplification development difficult problem. In the maximum power setting conditions, open communication distance of up to 2000 meters. Module comes with CRC check, so that anti-interference and sensitivity are greatly enhanced, the module provides a number of channel selection, online modification of the serial port rate, transmit power, RF rate and other parameters, the second development is simple and convenient, of course, can Through the MCU to set the general parameters, the module voltage range of 2.1-3.6V, suitable for battery-powered, and handheld device application development. Interface is simple, easy to use, because the standard UART protocol, even if the module is discontinued, the follow-up will be the same as the interface definition transparent module can be directly replaced, upgrade, and wireless re-write the driver! So users use WLK-485 to design wireless terminal products, without worrying about chip shortages, discontinued, with the use of other chips brought about re-programming troubles. Sensitivity high distance, even if the airspeed greater than 50kbps wall performance and distance is still perfect.
