E90-DTU(900SL 33) 868.125MH z 2 16 LoRa amplification of anti-interference Suitable for distant, easily disturbed environments

★ Note: In sunny weather, no shelter in the open environment. 12V / 2A power supply, 5 dBi suction cup antenna. the antenna is 2 meters away from the ground height, using the factory default parameters.

Frequency range and channel number

Model Default Frequency Band Range Channel Spacing Description
Hz Hz Hz
E90-DTU(900SL33) 868.125MHz 850.125- 930.125MHz IM 81. Half duplex

★ Note: In the same area, multiple sets of transmission stations are used to communicate one to one at the same time. It is sueeested that the channel interval be set above 2 MHz.

Transmit power level

Model 2W 1W 500m W 250m W
E90-DTU(900SL33) Factory default

★ Note: The lower the transmission power is, the closer the transmission distance is, but the working current will not decrease in the same proportion, so it is recommended to use the maximum transmission power.

Air rate grade

Model Default Equal series Air rate grade

E90-DTU(900SL33) 2.4k 6 2.4、4.8、9.6、19.2、38.4、62.5k

★ Note: The higher the air speed setting, the faster the transmission rate, and the closer the transmission distance; so if the rate meets the usage requirements, the lower the air speed, the better.
