Description
USB-TO-LoRa — Wireless Data Transmission Module
The USB-TO-LoRa data transmission module is based on the SX1262 chip. It does not require driver installation and is compatible with various operating systems. It supports multiple operating modes, is compact, and convenient to use. Designed for data acquisition in industrial and agricultural applications.
Version Options
USB-TO-LoRa-HF
USB-TO-LoRa-LF
HF version — 850–930 MHz band (Europe, America, Oceania). LF version — 410–510 MHz band (Asia and Europe). Please choose the version according to local radio frequency regulations before ordering.
USB-TO-LoRa-HF-B
USB-TO-LoRa-LF-B
The -B version uses an XTAL crystal oscillator — recommended operating temperature 0–50℃. The standard version uses TCXO — recommended operating temperature 0–85℃.
External Antenna Support
868/915 MHz Magnetic Antenna
Cable length: ~3 m
433/470 MHz Magnetic Antenna
Cable length: ~3 m
* For reference only. Magnetic antennas are not included. Purchase separately if you plan to use the module outdoors.
Key Features and Advantages
The USB-TO-LoRa-xF module is a wireless data transmission device with a USB interface based on the SX1262 module. It uses LoRa modulation/demodulation technology with the advantages of strong anti-interference capabilities and long-range communication (up to 5 km). It supports point-to-point, point-to-multipoint, relay networks, and AES encryption. It is compact and easy to install.

Main Function: USB → LoRa
Supports data transmission from USB to the wireless LoRa channel and vice versa.
LoRa Spread Spectrum Technology
Unlike traditional communication methods, CSS (Chirp Spread Spectrum) and FHSS (Frequency Hopping Spread Spectrum) technologies significantly improve communication range and anti-interference capabilities. Widely used in military and industrial communication systems.
Multiple Communication Methods — Software Configuration
Relay Network
The radio supports a multi-level relay network — suitable for ultra-long-distance communication or in complex terrain. Allows multiple networks to be organized in the same region.
AT Command Mode
Users can query the current module status or configure parameters by sending AT commands.
AES Encryption
The secret key is writable but not readable. Devices with encryption enabled and the same key can communicate normally — this provides an enhanced level of security.
Listen Before Talk (LBT)
Before transmitting, the module actively monitors the noise level in the channel. If the noise exceeds a threshold, transmission is delayed. This feature improves communication success in challenging environments, suitable for network transmission and collision avoidance.
Received Signal Strength Indication (RSSI)
Supports serial port output of the data packet signal strength — for signal quality assessment, network optimization, and distance measurement. Also supports background noise level output for manual implementation of LBT function.
High-Quality Components
Only verified components are used for stable operation of the communication module.
