Ebyte E22-400T33S UART 433~470MHz 33dBm LoRa Wireless Module

Ebyte E22-400T33S UART 433~470MHz 33dBm LoRa Wireless Module

E22-400T33S is a wireless serial port module (UART) based on SEMTECH's LoRa solution, with an operating frequency of 410.125~493.125MHz (default 433.125MHz), TTL level output, and is compatible with 3.3V and 5V IO port voltages.

Datasheet

Features

• Based on SEMTECH's high-performance RF chips, a new LoRa spread-spectrum modulation technology was developed, which brings a longer communication distance and stronger anti-interference ability.
• It supports automatic relay networking, multi-level relay is suitable for ultra-long-distance communication, and multiple networks run in the same area at the same time
• It supports users to set their own communication keys and cannot be read, which greatly improves the confidentiality of user data
• Support LBT function, listen to the channel environmental noise before transmission, which can greatly improve the communication success rate of the module in harsh environments
• Support RSSI signal strength indication function for evaluating signal quality, improving communication networks, and ranging
• Support wireless parameter configuration, send command packets wirelessly, and remotely configure or read wireless module parameters
• Supports wake-on-air, i.e., ultra-low-power function, suitable for battery-powered applications
• Support fixed-point transmission, broadcast transmission, channel monitoring
• It supports deep sleep, and the power consumption of the whole machine in this mode is about 2uA.
• Support global license-free ISM 433MHz frequency band and 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 re-powering
• Efficient watchdog design, once an exception occurs, the module will automatically restart, and can continue to work according to the previous parameter settings
• Support 2.4K~62.5kbps data transmission rate
• Support 2.3~5.5V power supply, more than 3.3V power supply can ensure the best performance
• Industrial-grade standard design, support long-term use at -40~+85°C
• The maximum power of the module can reach 2W (33dBm), and the transmission is longer and more stable.
