The EByte E22-400T22S is a professional-grade LoRa transceiver module built for demanding IoT deployments. It leverages Semtech’s LoRa spread spectrum modulation to deliver exceptional range and signal robustness, capable of penetrating urban and suburban environments where traditional RF links fail. The module’s core strength lies in its balance of high output power and low operational current draw, enabling long-term field deployment without frequent battery changes.
Integration is simplified through a standard asynchronous serial UART interface, which handles all packetization and RF management internally. This allows developers to focus on application logic without deep RF expertise. The module supports a wide operational frequency range from 410.125MHz to 493.125MHz, providing flexibility for regional ISM band compliance. Its compact PCB footprint and light weight make it an optimal choice for retrofitting existing equipment or designing new, miniaturized wireless sensor platforms.
