Rail-Mount LoRa Data Transfer Unit
Industrial Rail-Mount Design, Small In Size, Easy To Install, And Cost-Effective

The LoRa Spread Spectrum Technology
Compared to traditional communication, LoRa Chirp Spread Spectrum (CSS) and Frequency Hopping Spread Spectrum (FHSS) technologies greatly improve the performance of long-range communication and anti-interference, widely used in military and industrial communication fields.

Multiple Communication Methods
Can Be Set Via Software

Relay Networking
The Radio Station Can Realize Multi-Level Relay Networking, Suitable For Ultra Long-Range Distance Or Complex Environment Networking Communication, Allows Multi Networking On The Same Region

High-Quality Components
For Stable Performance Of Communication Module


Original chip SX1262	Industrial grade crystal oscillator -40 ~ 85℃

AT Command Mode
Users Can Query The Current Status Of The Module Or Set Parameters By Sending AT Commands

AES Communication
The Secret Key Is Writable But Unreadable, The Devices With The Encrypted Transmission Enabled And The Same Key Can Communicate With Each Other Normally For Greater Security

Listen Before Talk (LBT)
The module will actively monitor the environmental noise of the channel before sending. If the noise exceeds the threshold, the sending will be delayed. This function can improve the communication success rate of the module in harsh environments, suitable for networking transmission and anti-collision processing

Receive Signal Strength Indication (RSSI)
Supports serial port output of data packet signal strength, can be used to evaluate signal quality, improve communication network, and measure distance. Supports serial port output of environmental noise signal strength, can be used to manually realize LBT function.

Temperature Compensated Crystal Oscillator

Ensure The Long Time Working Of The Module Without Frequency Shift At The High
And Low Temperature Environment Of Industry

Multiple Protection, Safe And Stable
Built-in TVS (transient voltage suppression tube) can effectively suppress the surge voltage and transient peak voltage in the circuit, lightningproof & ESD protection. Built-in resettable fuse and protection diode to ensure stable output of current and voltage, prevents over-current and over-voltage proof, improve shock resistance
