433.125MHz Lora Wireless Data Transmission Modem RS485 RS232 E90-DTU(400SL42) 15W 30KM Relay Network LBT RSSI Watchdog - EBYTE

• Environmental field strength dynamic indication, data packet RSSI dynamic indication. Software and hardware dual watchdog. Dustproof and moisture proof. The product is simple and easy to use, with host computer configuration software. Using the latest LoRa technology, the distance is farther than the traditional LoRa data transmitter, and the performance is more powerful. Military-grade LoRa modulation technology is adopted, with data encryption and adjustable subpacket length. Super large single package, up to 240 bytes. Simple and high-efficiency power supply design, using crimp wire, supporting 12V power supply. Transmitting power up to 15W. Multi-level relay networking can be realized, the communication distance can be effectively extended, and ultra-long-distance communication can be realized. Using temperature compensation circuit, the frequency stability is better than ±1PPM. All aluminum alloy shell, compact size, easy installation, good heat dissipation. perfect shielding design, good electromagnetic compatibility, strong anti-interference ability. Powerful software functions, all parameters can be set by programming: such as power, frequency, air rate, address ID, etc.. Temperature monitoring, antenna abnormality monitoring. Support LBT function, the radio automatically waits for transmission according to the current environmental noise intensity. Greatly improve the communication success rate of the module in harsh environments. Support communication key function to effectively prevent data from being intercepted.
