JDY-41 Wireless 2.4G Serial Port Module

JDY-41 is developed by 2.4G technology, with a visual distance of 160 meters, serial port transparent transmission, switching value control, low power remote control and learning remote control. In particular, JDY-41 and JDY-40 are only compatible with each other on PCB package, while the communication protocol is completely different. For JDY-41 long-distance transparent transmission communication, each packet of data is checked, the receiver will not receive random code data, and the communication distance has been greatly improved. The measured communication distance is 160 meters, and the transparent transmission does not lose packets. It supports the serial port to send instructions to control the high and low level of GPIO pin at the receiving end, serial communication supports the transparent serial port communication, and communicates with the sending instruction serial port. Serial port transparent communication means that there is no format for the serial port communication between the transmitter and the receiver. The receiver will receive all the data input from the serial port of the transmitter. Instruction serial communication supports device communication with target address in front of data, and transparent communication supports ack response communication. The transmitter transmits the data to the receiver, and the transmitter will know whether the receiver has received the data. The learning remote control supports the receiver to learn the ID code of the transmitter. After successful learning, the receiver of the remote control will only accept the specified remote control.
