Ebyte E22-900T22U SX1262 900MHz 22dBM 5Km USB to LoRa Wireless Serial Module

E22-900T22U is a new generation of LoRa wireless spread spectrum module, based on the wireless serial port module designed by SEMTECH company SX1262 chip solution. It has a variety of transmission methods, works at 850.125~930.125MHz (default 868.125MHz), LoRa spread spectrum technology, 5V IO port voltage, and adopts USB standard packaging, which is convenient for users to develop and use. The communication is compatible with E22-230T/400T/900T series products, and supports a baud rate of 1200~115200 bps. Support functions such as wireless configuration, carrier sense, automatic relay, communication key, firmware upgrade, etc.

Datasheet

Features

• New LoRa spread spectrum modulation technology developed based on SEMTECH's SX1262/SX1268 RF chips, bringinglonger communication distance and stronger anti-interference capability.
• Support automatic relay networking, multi-level relay for ultra-long distance communication, and multiplenetworks running simultaneously in the same area.
• Support for user-set communication keys, and cannot be read, greatly improving the confidentiality ofuserdata.
• Supporting LBT function, listening to channel environment noise before sending, which can greatly improvethe communication success rate of the module in harsh environment.
• Support RSSI signal strength indication function for evaluating signal quality, improving communication network and ranging.
• Support wireless parameter configuration, send command packets through wireless, remote configurationorread wireless module parameters.
• Support for fixed-point transmission, broadcast transmission, channel monitoring.
• Communication distance up to 5km under ideal conditions.
  
• Parameter power-down saving, the module will work according to the set parameters after re-powering.
• Support for IAP firmware upgrade function.
• Efficient watchdog design, in case of abnormality, the module will restart automatically and can continueto work according to the previous parameter settings. 
• E22-900T22U supports data transfer rates of 2.4k to 62.5kbps.
• USB standard interface, plug and play.
• Supports 4.8 to 5.5V power supply, and any power supply greater than 5V can ensure the best performance.
• Industrial-grade standard design, supporting long time use under -40～+85℃.
• SMA antenna interface, can be easily connected to external antennas.
• Baud rate support 1200, 2400, 4800, 9600 (default), 19200, 38400, 57600, 115200 bps.
