E90-DTU(900SL42)LoRa data transmission radio LoRa module remote communication SX1262 radio frequency chip 485/232 wireless data transmission radio relay network

[Transmitting power]:15W

[Communication distance]:30km

[Product weight]: 425±5g

[Introduction]:E90-DTU(900SL42) is a truly high-quality industrial-grade wireless data transmission radio. The radio uses LORA spread spectrum technology. Its strong anti-interference ability makes wireless communications more stable and reliable in industrial sites. It has a variety of transmission methods and works in the (850.125~930.125MHz) frequency band (default 868MHz). The radio station provides a transparent RS232/RS485 interface. LoRa direct sequence spread spectrum technology will bring longer communication distance and has the advantage of strong anti-interference ability. The module has a software FEC forward error correction algorithm, which has high coding efficiency and strong error correction capability, which greatly improves reliability and transmission distance. The radio has data encryption function; supports sub-packet length setting, supports different real-time and data packets.

Frequency range and number of channels


Model specifications  Default frequency (Hz)  Frequency band range (Hz)  Channel spacing (Hz)  Number of channels
E90-DTU(900SL42) 868.125M 850.125~930.125M 1M 81, half duplex


Note: When using multiple groups of digital radio stations to communicate one-to-one at the same time in the same area, it is recommended that each group of digital radio stations set a channel spacing of more than 2MHz.

Transmit power level


Model specifications 10/15 W
E90-DTU(900SL42) Software adjustable, default 15W

Air speed class

Model specifications  Default air rate (bps)  Number of levels  Air rate level (kbps)
E90-DTU(900SL42) 2.4k 8 0.3、1.2、2.4、4.8、9.6、19.2、38.4、62.5

Note: The higher the air speed setting, the faster the transmission rate and the shorter the transmission distance; therefore, when the speed meets the usage requirements, it is recommended that the lower the air speed, the better.

Current parameters


Model specifications  Power supply voltage (V)  Emission current (A)  Waiting current (mA)
E90-DTU(900SL42) 12±1 2.5~3.5 30

Model specifications  Cache size  Packaging method
E90-DTU(900SL42) 1000 bytes Subpackage 32/64/128/240 bytes can be set by command to send

Note: 1. If the data received by the radio in a single time is greater than the single packet capacity, the excess data will be automatically allocated to the second transmission until the transmission is completed;

2. The data received by the radio station at a time cannot be larger than the buffer capacity.
