Product Descriptions
E22-900T33S is a new generation of Lo Ra wireless module. It is a wireless serial module ( UART ) based on SX1262 RF chip.Spread spectrum
technology, TTL level output, compatible with 3.3V and 5V IO port voltage.
E22-900T33S adopts a new generation of LoRa spread spectrum technology. Compared with the traditional SX127 6 solution, the SX1262
solution has a longer transmission distance, faster speed, lower power consumption, and smaller size; it supports air wake-up, wireless
configuration, and carrier sense. , automatic relay, communication key and other functions, support subpackage length setting, and can provide
customized development services.
Product Applications
• Home security alarm and remote keyless entry;
• Smart home and industrial sensors, etc.;
• Wireless alarm security system ;
• Building automation solutions;
• Wireless industrial grade remote control;
• healthcare products;
• Advanced Meter Reading Infrastructure (AMI );
• Automotive industry applications.
Product Features
• Based on SX1262 , a new Lo Ra spread spectrum modulation technology is developed , which brings 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 run simultaneously in the same area ;
• Support users to set the communication key by themselves, and it cannot be read, which greatly improves the confidentiality of user data;
• Support LBT function , monitor the channel environment noise before sending, which can greatly improve the communication success rate of the module in harsh environments ;
• Support RSSI signal strength indication function , used to evaluate signal quality, improve communication network, distance measurement;
• Support wireless parameter configuration, send command packets wirelessly, remotely configure or read wireless module parameters ;
• Support air wake-up, that is, ultra-low power consumption function, suitable for battery-powered applications;
• Support fixed-point transmission, broadcast transmission, channel monitoring;
• Support deep sleep, the power consumption of the whole machine is about 4uA in this mode ;
• Support global license-free ISM 868/915 MHz frequency band ;
• The module has built-in PA + LNA , and the communication distance can reach 16 km 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 data transmission rate of 2.4k ~ 62.5k bps ;
• Support 3.3 ~ 5.5V power supply, power supply greater than 5V can guarantee the best performance;
• Industrial-grade standard design, supporting long-term use at -40 ~ + 85 ℃;
• Dual antennas are optional ( IPEX/ stamp hole) , which is convenient for secondary development and integration.
