Conoce más detalles

It is a wireless data transfer unit with USB interfaces based on the SX1262 module,with XTAL Crystal Oscillator. Adopts LoRa Modulate and Demodulate technology, with the advantages of anti-interference and long-distance communication (up to 5KM) 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 --Allow to be set via software ( Stream transfer mode, Packet transfer mode). AT Command Mode--Users can query the current status of the module or set parameters by sending AT commands 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 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 Actual test environment-- Sunny weather with an open field, 22dBm emit power, airspeed 0.3kbps, 6dBi magnetic CB antenna, 3m antenna height, 5km distance 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 Supports point-to-point, point-to-multipoint, relay network, AES, etc. Compact size and easy to install, suitable for the wire-less data transmission and device control of industry standard or non-standard user protocol
