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 level output, 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.
