Waveshare USB To LoRa Data Transfer Module, SX1262 - 24515 - USB-TO-LoRa-HF The USB-TO-LoRa-xF is a wireless data transfer unit with USB interfaces based on the SX1262 module. 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 wireless data transmission and device control of industry-standard or non-standard user protocols. Features Adopts LoRa Modulate and Demodulate technology, anti-interference, and long-distance communication Adopts the original SX1262 chip, with -148dBm reception sensitivity and 22dBm emitt power Supports preamble detection, with CRC, automatic packetization, and 960-byte cache functions Supports LBT sending, RSSI output, AT command configuration AES communication to ensure data transmission security Supports multi-level relay networking to increase the wireless communication distance Supports host configuration and firmware upgrade (supports firmware customization for batch order) Comes with online resources and a manual The LoRa Spread Spectrum TechnologyCompared 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 NetworkingThe 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 ModeUsers Can Query The Current Status Of The Module Or Set Parameters By Sending AT Commands. AES CommunicationThe 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, which can be used to manually realize the LBT function.
