Functional Features

☆ Transmission power 5W, high receiving sensitivity -128dBm.

Receive current<100mA, 5W: transmit current<2A.

☆ Modulation method: LORA， The carrier frequency is 230MHz.

☆ Based on LORA modulation method, using efficient communication protocol, with a channel error rate of10^-2When, the actual bit error rate can be obtained10^-5～10^-6.

In line of sight conditions, the antenna height is greater than 8 meters and the reliable transmission distance is over 10Km.

Provide a transparent data interface that can adapt to any standard or non-standard user protocol. Automatically filter out noise signals and false data generated in the air (what is sent is received).

The standard configuration of JZX2302 radio station provides 64 channels, meeting the needs of users for multiple communication combinations. JZX2302 radio can provide 1200bps in the air 4800bps There are five communication baud rates: 9600bps, 19200bps, and 38400bps. The serial port can provide 1200bps There are seven interface baud rates of 4800bps, 9600bps, 19200bps, 38400bps, 57600bps, and 115200bps, and the wireless transmission rate is proportional to the interface baud rate to meet the needs of customer devices for multiple baud rates.

The maximum amount of data transmitted at the same speed in the serial port and air can reach 5K bytes.

Even with half duplex communication, users do not need to write extra programs. They only need to receive/send data from the interface. Other operations such as over the air conversion, network connection, control, etc. can be automatically completed by the radio.

☆ Adopting high-performance single-chip processors, with fewer peripheral circuits, high reliability, and low failure rates.

The watchdog monitors internal functions, changes the organizational structure of traditional products, and improves product reliability.
