The E22-900T22S is a brand - new generation of LoRa wireless module. It is a wireless serial port module (UART) based on the SX1262 RF chip from SEMTECH. It has multiple transmission modes, operates in the (850.125 - 930.125MHz) frequency band (default 868.125MHz), utilizes LoRa spread - spectrum technology, features TTL level output, and is compatible with IO port voltages of both 3.3V and 5V.

The E22 - 900T22S adopts the latest generation of LoRa spread - spectrum technology. Compared with the traditional SX1276 solution, the SX1262 solution offers a longer transmission distance, higher speed, lower power consumption, and a smaller size. It supports functions such as wake - on - air, wireless configuration, carrier sense, automatic relay, and communication keys. It also supports the setting of packet length and can provide customized development services.

Communication Features and Functions of the LoRa Module

  • It is developed based on the SX1262 with a new LoRa spread - spectrum modulation technology, enabling a longer communication distance and stronger anti - interference ability.

  • It supports automatic relay networking. Multi - level relays are suitable for ultra - long - distance communication, allowing multiple networks to operate simultaneously in the same area.

  • It allows users to set their own communication keys, which cannot be read, greatly enhancing the confidentiality of user data.

  • It supports the LBT carrier sense function. It monitors the channel environmental noise before sending, which can significantly improve the communication success rate of the module in harsh environments.

  • It supports the RSSI signal strength indication function, which can be used to evaluate signal quality, improve communication networks, and measure distances.

  • It supports wireless parameter configuration. Wireless instruction data packets can be sent to remotely configure or read the parameters of the wireless module.

  • It supports wake - on - air, an ultra - low - power consumption function suitable for battery - powered application scenarios.

  • It supports point - to - point transmission, broadcast transmission, and channel monitoring.

  • It supports deep sleep mode, with the overall power consumption of the module being approximately 2uA in this mode.

  • It supports the global license - free ISM868/915MHz frequency bands.

  • Under ideal conditions, the communication distance can reach 5.5km.

  • The parameters are saved even when the power is off. After power - on, the module will operate according to the set parameters.

  • It has an efficient watchdog design. In case of an abnormality, the module will automatically restart and continue to operate according to the previous parameter settings.

  • It supports a data transmission rate of 2.4K - 62.5kbps.

  • It supports a power supply of 2.3 - 5.5V, and a power supply greater than 3.3V can ensure optimal performance.

  • It is designed to industrial standards and can be used for a long time in the temperature range of - 40 to + 85°C.

  • It offers a choice of two antennas (IPEX/stamp holes), facilitating secondary development by users and integration.
