Hot selling E22-400T33E SX1268 33dBm 16km UART/RS485/RS232/USB interface Wireless LoRa spread spectrum module
E22-400T33E is a new generation of LoRa wireless spread spectrum module designed based on the SX1268 chip solution
Product Descriptions
E22-230T30E, E22-230T33E, E22-400T30E, E22-400T33E are the new generation of LoRa wireless spread spectrum modules. Among them, E22-230T30E and E22-230T33E are based on the wireless serial port module designed by SEMTECH's SX1262 chip
scheme, while E22-400T30E and E22-400T33E are based on SX1268 chip scheme. It has a variety of transmission modes. E22-230T30E and E22-230T33E work in the 220.125 ~ 236.125MHz frequency band (230.125MHz by default), E22-400T30E and E22-
400T33E work in the 410.125 ~ 493.125MHz frequency band (433.125MHz by default), LoRa spread spectrum technology, compatible with 3.3V and 5V IO port voltage, MINI PCI-e standard packaging, UART/RS485/RS232/USB communication interface
selection, and communication is compatible with E22-T series products, facilitating user development and use.
E22-230T30E , E22-230T33E , E22-400T30E , E22-400T33E adopt a new generation of LoRa spread spectrum technology. Compared with the traditional SX1278 solution, this solution has a longer transmission distance and faster speed; it supports air
wake-up, wireless configuration, and carrier monitoring , automatic relay, communication key and other functions, support subpackage length setting, and can provide customized development services.

Product Features
• On the new LoRa spread spectrum modulation technology developed by SEMTECH 's SX1262 and SX1268 RF chips , it brings longer communication distance and stronger anti-interference ability;
• Automatic relay networking, multi-level relay is suitable for ultra-long-distance communication, and multiple networks run simultaneously in the same area;
• Support users to set the communication key by themselves, and it cannot be read, which greatly improves the confidentiality of user data;
• Support LBT function, monitor the channel environment noise before sending, which can greatly improve the communication success rate of the module in harsh environments;
• Support RSSI signal strength indication function , used to evaluate signal quality, improve communication network, distance measurement;
• Wireless parameter configuration, send command packets wirelessly, remotely configure or read wireless module parameters;
• Support air wake-up, that is, ultra-low power consumption function, suitable for battery-powered applications;
• Fixed-point transmission, broadcast transmission, channel monitoring;
• Support deep sleep, the power consumption of the whole machine is about 2mA in this mode ;
• Support UART /RS485/RS232/USB communication interface selection, single output;
• E22-400T30E and E22-400T33E support global license-free ISM 433MHz frequency band , and support 470MHz meter reading frequency band;
• E22-230T30E and E22-230T33E support 230MHz power frequency band;
• The module has built-in PA+LNA , and the communication distance can reach 8km~12km under ideal conditions ;
• The parameters are saved after power-off, and the module will work according to the set parameters after power-on;
• High-efficiency watchdog design, once an exception occurs, the module will automatically restart and continue to work according to the previous parameter settings;
• E22-400T30E and E22-400T33E support the data transmission rate of 2.4k ~ 62.5kbps ;
• E22-230T30E and E22-230T33E support the data transmission rate of 2.4k ~ 15.6kbps ;
• 3.3 ~ 5.5V power supply, power supply greater than 5V can guarantee the best performance;
• Industrial-grade standard design, supporting long-term use at -40~+85 ℃;
• The first -generation IPEX interface can be easily connected to an external antenna. The baud rate supports 1200 , 2400 , 4800 , 9600 (default), 19200 , 38400 , 57600 , 115200 bps .
• Communication is compatible with E22-T series products.
