JDY-41 is developed using 2.4G technology, with a viewing distance of 160 meters, serial port transparent transmission, switch control, low-power remote control, and learning remote control. In particular, JDY-41 and JDY-40 are only compatible with PCB packaging, and the communication protocol is complete. It is different. JDY-41 has long-distance transparent transmission communication. Every packet of data is verified. The receiving end will not receive garbled data. The communication distance has been greatly improved. The measured communication distance is 160 meters without loss. Package, support the serial port to send commands to control the high and low levels of the GPIO pins on the receiving end, serial communication supports transparent serial communication, communicate with the serial port that sends instructions, transparent serial communication means that the transceiver serial communication has no format, what the transmitter sends, the receiver will receive For all the data input by the serial port of the transmitter, the command serial communication supports the device communication by adding the target address in front of the data, and the transparent transmission communication supports ACK response communication. The transmitter transparently transmits the data to the receiver, and the transmitter will know whether the receiver has received it or not. , The learning remote control supports the receiving end to learn the ID code of the transmitting end. After the learning is successful, the receiving end of the remote control will only accept the designated remote control.
