Hot selling E22-400T30D SX1268 UART 10Km Range 433Mhz 30dBm DIP 24*43mm CE RoHs FCC TCXO LoRa RF Module

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.
