1: Introduction
1.1 Brief Introduction
E22-230T33S is a new generation of LoRa wireless module, this
module (UART) is based on SEMTECH high performance RF chip,
transmitting power of 33 dBm, with a variety of transmission modes,
working in (220.125~236.125MHz) band (default 230.125MHz), LoRa
frequency expansion technology, TTL level output, compatible with 3.3V
and 5V IO port voltage.
E22-230T33S adopts the new generation LoRa frequency expansion
technology, faster, lower power consumption and smaller volume; support
air wake up, wireless configuration, carrier monitoring, automatic relay, communication key and other functions, support
subcontract length setting, can provide customized development services.
1.2 Features
 Based on the SEMTECH high-performance RF chip, the development of a new Lo R a spread frequency
modulation technology, bring further communication distance, anti-interference ability is stronger;
 Support automatic relay networking, multi-level relay is suitable for long-distance communication, the same area
running multiple networks running at the same time;
 Support users to set the communication key, and can not be read, greatly improve the confidentiality of user data;
 Support the LBT function, and monitor the channel environment noise before sending, which can greatly improve
the communication success rate of the module in the harsh environment;
 Support RSSI signal strength indication function for assessing signal quality, improving communication network
and ranging;
 Support wireless parameter configuration, through wireless sending command packet, remote configuration or
reading wireless module parameters;
 Support air wake-up, that is, ultra-low power consumption function, suitable for the application scheme of battery
power supply;
 Support fixed-point transmission, broadcast transmission, and channel monitoring;
 Support deep dormancy, the power consumption of the whole machine is about 2 uA;
 Support 230 MHz power frequency band, penetration diffraction ability is stronger than 433 MHz;
 The module has built-in PA + LNA, with the communication distance up to 16km under ideal conditions;
 The parameters are saved, and the module will work according to the set parameters;
 Efficient watchdog design, in case of abnormal, the module will automatically restart, and can continue to work
according to the previous parameter Settings;
 Support the data transmission rate of 2.4k ~15.6k bps;
 Support 3.3~5.5V power supply, more than 5V power supply can ensure the best performance;
 Industrial grade standard design, support-40~ + 85℃ for a long time to use;
 Dual antenna optional (IPEX / stamp hole), easy for secondary development and integration.
