Feature(may vary by option.)
●Features: All core components are originally imported, our transceiver modems have much advanced features with smaller size and lower cost. ★ The top TX power is 100mW, all technical parameters meet European industry standards.
●Temperature compensators are used to make the frequency stability better than ± 1.5 ppm. ★ Operating temperature range: -40℃~+85℃, applicable to various harsh environments, these are real industrial products.
●Aluminum alloy body, compact size, large heat distribution; good shielding, first-class electromagnetic compatibility and strong anti-interference. ★ Power reverse & overload protection and antenna surge protection functions significantly improve reliability.
●Parameters can be configured by programming, such as TX power, frequency point, air data rate, address and so on. ★ Very low power consumption, standby current is only 28mA (even lower under power saving and sleep mode), TX current ≤0.2A. ★ Embedded watch dog and precise time layout, modem automatically restarts in abnormal situation and works with previous parameters.
●The transceivers use the original SEMTECH SX1276 chip, customers come the products due to the high reliability.

Description
Frequency: 862~893MHz [Power]: 20dBm [Distance]: 3.0km [Interface]: RS232/RS485 [Introduction]: E32-DTU (868L20) is a 868M wireless data transceiver with standard connectors. They are half duplex. TX & RX modems with LoRa technology and transparent transmission mode. Voltage ranges from 8V to 28V, Operating Frequency: 862~893MHz (Standard: 868MHz) LoRa Direct Sequence Spread Spectrum technology allows for longer communication distance and better power density concentration as well as superior anti-interference capability. The FEC algorism allows for higher coding efficiency and correction capability. The interfered data packets are proactively corrected in the event of sudden interference, which greatly improves reliability and communication distance. Without FEC the disrupted data of a package will drop. The transceivers feature data encryption and compression. The data transmitted in the air is random, the strict algoris m makes data capture pointless. The data compression function has the ability to reduce data transfer time, which in turn reduces the possibility of interference, improving reliability and communication efficiency.
