Product Descriptions

E22-230T22U, E22-400T22U and E22-900T22U are the new generation of LoRa wireless spread spectrum modules, of which E22-230T22U and E22-900T22U modules are wireless serial modules designed based on SEMTECH's SX1262 chip solution, while 

E22-400T22U module is based on SX1268 chip scheme design. With multiple transmission modes, it works in 220.125MHz~236.125MHz (default 230.125MHz), 410.125~493.125MHz (default 433.125MHz), 850.125~930.125MHz band (default 868.125MHz), LoRa spread spectrum technology, 5V of IO port voltage, using USB standard package, convenient for user development and use. Communication compatible with E22-230T/400T/900T series products, support baud rate 1200 ~ 115200 bps.

E22-230T22U, E22-400T22U, E22-900T22U adopt the new generation LoRa spread spectrum technology, compared with the traditional SX1278 solution, this solution has longer transmission distance and faster speed; it supports wireless configuration, 

carrier listening, automatic relay, communication key, upgrade firmware and other functions, supports sub-packet length setting, and can provide custom development service.

Product Features

? New LoRa spread spectrum modulation technology developed based on SEMTECH's SX1262/SX1268 RF chips, bringing longer communication distance and stronger anti-interference capability. 

? Support automatic relay networking, multi-level relay for ultra-long distance communication, and multiple networks running simultaneously in the same area. 

? Support for user-set communication keys, and cannot be read, greatly improving the confidentiality of user data. 

? Supporting LBT function, listening to channel environment noise before sending, which can greatly improve the 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 configuration or read wireless module parameters. 

? Support for fixed-point transmission, broadcast transmission, channel monitoring. 

? E22-400T22U supports global license-free ISM 433MHz band and supports 470MHz meter reading band. 

? 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 continue to work according to the previous parameter settings. 

? E22-230T22U supports data transmission rates from 2.4k to 15.6kbps. 

? E22-400T22U supports data transfer rates from 2.4k to 62.5kbps. 

? 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. 

? Communication compatible with E22-230T/400T/900T series products.
