E22-230T22D SX1262 LoRa wireless serial port module
E22-230T22D is a new generation of LoRa wireless module.
Product Descriptions
E22-230T22D is a new generation LoRa wireless module, based on SEMTECH SX1262 RF chip wireless serial module (UART), with a variety of transmission methods, working in the (220.125 ~ 236.125MHz) frequency band (default 230.125MHz), LoRa spread spectrum technology, TTL level output, compatible with 3.3V and 5V IO port voltage.
E22-230T22D adopts the new generation LoRa spread spectrum technology, compared with the traditional SX1276 solution, SX1262 solution has longer transmission distance, faster speed, lower power consumption and smaller size; it supports wake-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);
• Automotive Industry Applications.
Product Features
• Develops new LoRa spread spectrum modulation technology based on SX1262, which brings 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 it 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, improving communication network and ranging;
• Supports wireless parameter configuration, sending command packets over the air to remotely configure or read wireless module parameters;
• Supports over-the-air wake-up, i.e., ultra-low power consumption function, for battery-powered application solutions;
• Supports fixed-point transmission, broadcast transmission, and channel monitoring;
• Supports deep hibernation, the power consumption of the whole unit in this mode is about 2uA;
• Supports 230MHz power band with better penetration and bypass capability than 433MHz;
• Communication distance up to 5km under ideal conditions;
• Parameters are saved at power-down, and the module will work according to the set parameters after re-powering;
• High efficiency watchdog design, in case of abnormality, the module will restart in automatically and can continue to work according to the previous parameter settings;
• Supports data transfer rates from 2.4k to 15.6kbps;
• Supports 2.3 to 5.5V power supply, and any power supply greater than 5V can ensure the best performance;
• Industrial standard design, supporting long time use at -40~+85℃; Dual antenna optional (IPEX/stamp hole), easy for users to secondary development, easy to integrate.h
