Hot selling E22-400T37S SX1262 433/470MHz 5W high power Relay networking LoRa wireless module
E22-400T37S is a new generation of LoRa wireless module based on SX1268 radio frequency chip wireless serial port module (UART)
Product Descriptions
E22-XXXT37S is a new generation of LoRa wireless module, wireless serial module (UART) based on SX126X RF chip, with multiple transmission modes, working in 230/433/470MHz band, LoRa spread spectrum technology, TTL leveloutput, supporting
4.5V - 15V power supply voltage.
E22-XXXT37S adopts the new generation LoRa spread spectrum technology, compared with the traditional SX1278 solution, SX126X is farther, faster, lower power consumption and smaller; it supports wake-up on air, wireless configuration, carrier
listening, automatic relay, communication key and other functions, supports sub-packet length setting, and can provide custom development services.
Product Applications
• home security alarms and remote keyless entry;
• Smart home as well as industrial sensors, etc.;
• wireless alarm security systems;
• building automation solutions;
• wireless industrial grade remote controls;
• Healthcare products;
• Advanced Meter Reading Architecture (AMI);
• Applications for the automotive industry.
Product Features
• Develop new LoRa spread spectrum modulation technology based on SX126X, bringing longer communication distance and stronger anti-interference capability;
• supports auto-relay networking, multi-level relay for ultra-long distance communication, and multiple networks running simultaneously in the same area;
• supports user-set communication key and cannot be read, which greatly improves the confidentiality of user data;
• supports LBT function to listen to the channel environment noise before sending, which can greatly improve the communication success rate of the module in harsh environment;
• supports RSSI signal strength indication function for evaluating signal quality and improving communication network;
• supports wireless parameter configuration, which can remotely configure or read wireless module parameters by sending command packets wirelessly;
• supports over-the-air wake-up, i.e., ultra-low power consumption function, for battery-powered application solutions;
• support for fixed-point transmission, broadcast transmission, and channel monitoring;
• supports deep hibernation in the full power supply range, the power consumption of the whole machine in this mode is less than 10uA;
• supports global license-free ISM 433MHz band and 230/470MHz meter reading band;
• Module built-in PA+LNA, communication distance up to 25km under ideal conditions;
• parameters are saved at power-down, and the module will work according to the set parameters after re-powering;
• efficient watchdog design, once the abnormality occurs, the module will restart automatically and can continue to work according to the previous parameter settings;
• supports data transmission rate from 0.3K to 62.5kbps;
• support 4.5 ~ 15V wide voltage power supply, the full power supply range can guarantee 37dBm power output;
• industrial standard design, support -40 ~ +85 ℃ under long time use;
• module power up to 5W (37dBm), farther and more stable transmission.
• module built-in under-voltage, overvoltage warning function and built-in warning LED.
• module built-in over-temperature protection function, automatically stop transmitting after exceeding the maximum temperature of the module.
• module bottom reserved matrix pads, convenient for secondary development of heat dissipation treatment.
