Waveshare USB to LoRa Data Transfer Module – SX1262

The USB-TO-LoRa-xF is a wireless data transfer unit with a USB interface, based on the SX1262 module. It adopts LoRa modulation and demodulation technology, offering strong anti-interference capabilities and long-distance communication (up to 5 km). It supports point-to-point, point-to-multipoint, relay networking, AES encryption, and more. With its compact size and easy installation, it is ideal for wireless data transmission and device control using industry-standard or custom user protocols.

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.

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.

Temperature compensated crystal oscillator

TCXO crystal oscillator ensures the long time working of the module without frequency shift at the extreme temperature environment of industry.

Actual test environment

Sunny weather with an open field, 22dBm emit power, airspeed 0.3kbps, 6dBi magnetic CB antenna, 3m antenna height, 5km distance.
