Product Descriptions

E22-400TXXX series is a new generation of LoRa wireless module. It is a wireless serial port module (UART) based on SX1268 RF chip, with a variety of transmission methods, working in (410.125 ~ 493.125MHz) frequency band (default 433.125MHz), 

LoRa spread spectrum technology, with TTL level output, support 2.3V - 5.5V supply voltage. 

E22-400TXXX adopts a new generation of LoRa spread spectrum technology. Compared with the traditional SX1278 solution, SX1268 has farther range, faster transmission speed, but with lower power consumption and smaller size;

It supports wake-up over the air, wireless configuration, LBT, automatic relay, communication key and other functions. It also supports packet length setting, and customized development service is available

Product Applications

? Home security alarm and remote keyless entry;

? Smart home and industrial sensors;

? Wireless alarm security system;

? Building automation solutions;

? Wireless industrial-grade remote control;

? Health care products;

? Advanced Meter Reading Architecture (AMI);

? Automotive industry applications.

Product Features

? Based on chip SX1268, the new LoRa spread spectrum modulation technology brings a longer communication distance and stronger anti-interference ability;

? Support automatic relay networking, multi-level relay is suitable for ultra-long-distance communication, and multiple networks can run simultaneously in the same area;

? User can set the communication key by himself and the key cannot be read by others. It greatly improving the confidentiality of user data;

? Support LBT function, monitoring the channel environment noise before sending data, which greatly improves the communication success rate of the module in harsh environments;

? Support RSSI signal strength indicator function for evaluating signal quality, improving communication network, and ranging;

? Support wireless parameter configuration, send command packets wirelessly, remotely configure or read wireless module parameters;

? Support wake-up over the air, that is ultra-low power consumption, suitable for battery-powered applications;

? Support point to point transmission, broadcast transmission, channel listening;

? Support deep sleep, the power consumption of the whole module is about 2uA in this mode;

? Support global license-free ISM 433MHz frequency band, support 470MHz meter reading frequency band;

? The module has built-in PA+LNA, and the communication distance can reach 16km under ideal conditions;

? The parameters are saved after power-off, and the module will work according to the set parameters after power-on;

? Efficient watchdog design, once an exception occurs, the module will automatically restart and continue to work according to the previous parameter settings;

? Support 2.4k～62.5kbps air data rate transmission;

? Support 2.3～5.5V power supply, power supply greater than 3.3V guarantees the best performance;

? Industrial standard design, supporting long-term use at -40～+85℃;

? The maximum power of the module can reach 2W (33dBm), which makes the transmission farther and more stable.
