Ebyte E22-400T37S UART 433/470MHz 37dBm 25KM High Power Relay Networking LoRa Wireless Module
E22-400T37S is a new generation of LoRa wireless module, wireless serial module (UART) based on SX126XRFchip, with multiple transmission modes, working in 433/470MHz band, LoRa spread spectrum technology, TTL level output, supporting 4.5V - 15V power supply voltage.
E22-400T37S adopts the new generation LoRa spread spectrum technology, compared with the traditional SX1278 solution, SX126X is farther, faster, lower power consumption and smaller; it supports wake-up on air, wirelessconfiguration, carrier listening, automatic relay, communication key and other functions, supports sub-packet length setting, and can provide custom development services.
Features
- Develop new LoRa spread spectrum modulation technology based on SX126X, bringing longer communication distanceand stronger anti-interference capability
- supports auto-relay networking, multi-level relay for ultra-long distance communication, and multiplenetworks running simultaneously in the same area
- supports user-set communication key and cannot be read, which greatly improves the confidentiality ofuserdata
- supports LBT function to listen to the channel environment noise before sending, which can greatly improvethe communication success rate of the module in harsh environment
- supports RSSI signal strength indication function for evaluating signal quality and improving communicationnetwork
- supports wireless parameter configuration, which can remotely configure or read wireless module parametersby sending command packets wirelessly
- supports over-the-air wake-up, i.e., ultra-low power consumption function, for battery-powered applicationsolutions
- support for fixed-point transmission, broadcast transmission, and channel monitoring
- supports deep hibernation in the full power supply range, the power consumption of the whole machine in this mode is less than 10uA
- supports global license-free ISM 433MHz band and 230/470MHz meter reading band;
- Module built-in PA+LNA, communication distance up to 25km under ideal conditions
- supports data transmission rate from 0.3K to 62.5kbps
- support 4.5 ~ 15V wide voltage power supply, the full power supply range can guarantee 37dBm power output
- industrial standard design, support -40 ~ +85 ℃ under long time use
- module power up to 5W (37dBm), farther and more stable transmission.
- module built-in under-voltage, overvoltage warning function and built-in warning LED.
- module built-in over-temperature protection function, automatically stop transmitting after exceedingthemaximum temperature of the module.
- module bottom reserved matrix pads, convenient for secondary development of heat dissipation treatment.
