433MHz Lora Wireless RF Module E22-400T37S 37dbm Long Distance 20KM Low Power LBT RSSI IPEX Stamp Holes PA+LNA

Description

• E22-400T37S is a new generation of LoRa wireless module, based on radio frequency chip wireless serial port module (UART), with a variety of transmission methods , working in (410.125~493.125MHz) frequency band (default 433.125MHz), LoRa spread spectrum technology, TTL Level output, support 4 5 V - 15V supply voltage
• E22-400T37S adopts a new generation of LoRa spread spectrum technology, farther, faster, lower power consumption, smaller size; Support air wake-up, wireless configuration, carrier monitoring, automatic relay, communication key and other functions, support subpacket length setting, and can provide customized development services
• Support automatic relay networking, multi-level relay is suitable for ultra-long-distance communication, and multiple networks run in the same area at the same time
• Support LBT function, listen to channel environmental noise before transmission, which can greatly improve the communication success rate of the module in harsh environments
• The module has built-in PA+LNA, and the communication distance can reach 20km under ideal conditions (16Km stable communication measured in urban environment);

Features and Functions
Support users to set their own communication keys and cannot be read, which greatly improves the confidentiality of user data;
Support wireless parameter configuration, send command data packets through wireless, remotely configure or read
wireless module parameters;
Support over-the-air wake-up, that is, ultra-low-power function, suitable for battery-powered applications;
Support fixed-point transmission, broadcast transmission, channel monitoring;
It supports deep sleep in the full power supply range, and the power consumption of the whole machine in this mode is less than 10uA;
Support the global license-free ISM 433MHz frequency band, support 470MHz meter reading band;
The module has built-in PA+LNA, and the communication distance can reach 20km under ideal conditions (16Km
stable communication measured in urban environment);
The parameters are saved when power down, and the module will work according to the set parameters after power on again;
Efficient watchdog design, once an exception occurs, the module will automatically restart and continue to work
according to the previous parameter settings;
The module has built-in undervoltage, overvoltage warning function and built-in warning LED.
The module has a built-in over-temperature protection function, and automatically stops sending after exceeding the
maximum temperature of the module.
The matrix pad is reserved at the bottom of the module to facilitate the heat dissipation processing of secondary
development.
