USB to LoRa HF Adapter SX1262 with TCXO 850 ~ 930MHz – Long-Range Wireless Communication Module

USB to LoRa Data Transfer Module SX1262 with TCXO – Long-Range Wireless Communication

The USB-TO-LoRa-HF module is a USB to LoRa HF adapter used for wireless data transmission, based on the SX1262 chip. It utilizes LoRa technology, offering high interference immunity and a long transmission range (up to 5 km). The version with the TCXO crystal oscillator ensures stable operation across a wide temperature range. The module is Plug & Play, requires no driver installation, and is ideal for data acquisition in the industrial and agricultural sectors.
A minimum of two units are required to form a communication network.

Key Features:

• SX1262-based solution – driver-free, Plug & Play
• Supports USB to LoRa communication
• LoRa modulation and demodulation technology – high anti-interference and long range (up to 5 km)
• SX1262 chip – -148dBm reception sensitivity and 22dBm transmit power
• Built-in functions: preamble detection, CRC, automatic packetization, 960 bytes buffer
• Support for LBT (Listen Before Talk) – improves transmission success in difficult environments
• RSSI (Receive Signal Strength Indication) output – signal quality assessment
• AES128 encryption – ensures data transmission security
• Supports multi-level relay networking – increases range
• Configuration via AT commands
• Compact ABS housing with USB Type A connector
• TCXO crystal oscillator version – stable operation in the 0 ~ 85℃ range

LoRa Spread Spectrum Technology

Compared to traditional communication, Chirp Spread Spectrum (CSS) and Frequency Hopping Spread Spectrum (FHSS) technologies significantly improve range and anti-interference, often used in military and industrial communication fields.

Relay Networking

The radio station can realize multi-level relay networking, ideal for ultra long-range communication or complex environments, allowing multiple networks in the same region.

AT Command Mode

Users can easily send AT commands to check the module's current status or configure its operating parameters.

AES Encryption

Devices with encryption enabled and the same key can communicate correctly, ensuring greater security.

Listen Before Talk (LBT)

The module actively monitors the ambient channel noise before sending. If the noise exceeds the threshold, transmission will be delayed. This function improves communication success in harsh environments.

Receive Signal Strength Indication (RSSI)

The RSSI function allows continuous monitoring of the received signal strength (data) and the ambient noise level. This information is available on the serial port, allowing the user to precisely evaluate connection quality, optimize network topology, and perform more accurate distance measurements. It also supports the output of ambient noise signal strength, which can be used for manual implementation of the LBT function.

Important Communication Notes

This product does not support the LoRaWAN protocol. The module only allows communication with the corresponding SX1262-LoRa-DTU-xF model. A minimum of two USB-TO-LoRa-HF modules are required to form a LoRa communication network (the same applies to the USB-TO-LoRa-LF version).

External Antenna Support

The module has an SMA connector, allowing the connection of an external antenna, such as an 868/915 MHz magnetic mount antenna with a cable length of approximately 3 m. This is particularly useful when the module is intended for outdoor use or in metal enclosures. Please note that external magnetic antennas are not included in the set and must be purchased separately.
