Adopts LoRa Modulate and Demodulate technology, with the advantages of anti-interference and long-distance communication (up to 5KM). Supports point-to-point, point-to-multipoint, relay network, AES, etc. Compact size and easy to install, suitable for the wireless data transmission and device control of industry standard or non-standard user protocol
Version Options
- USB-TO-LoRa-HF
- USB-TO-LoRa-LF
- USB-TO-LoRa-HF-B
- USB-TO-LoRa-LF-B
*The HF version is 850~930MHz frequency for Europe, America and Oceania, and the LF version is 410~510MHz frequency for Asia and Europe, please select the frequency version according to the local radio regulations before placing order.
*The USB-TO-LoRa-xF-B uses XTAL crystal oscillator and is recommended to be used in 0~50? temperature, while USB-TO-LoRa-xF uses TCXO crystal oscillator and is recommended to be use in 0~85? temperature.

Primary function - Supports USB To LoRa
- 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.
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
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.
High-quality Components
- For stable performance of communication module
- Original chip SX1262
- Industrial grade crystal oscillator -40 ~ 85? (TCXO version)
Temperature Compensated Crystal Oscillator
- Ensure the long time working of the module without frequency shift at the extreme temperature environment of industry
(This function is only available in the TCXO crystal oscillator version)
