FEATURES

Frequency Range: 868/915 MHz (Sx1276) Based LoRa modulation techniques. Half-duplex communications, serial data transparent transmission. Embedded MESH distributed MANET protocols. Each communication has multiple handshake confirmation, to ensure the stability of the data. Production free debugging, 3.4-5.5V voltage range can be customized 2.1-3.6V. Micro-power transmission, standard 100mW, 7-Level adjustable. Receive sensitivity up to -148dBm, the maximum transmit power + 20dBm. High-efficiency forward error correction coding techniques and frequency hopping mechanism, anti-interference ability, low error rate. Support Serial wake, ready to send and receive data, no periodic wake-up time. Support Air wake AUX signal given by the module, Wake user device. CAD detection LoRa signal, to prevent accidental wake. Communication protocol conversion and RF transceiver to switch automatically, without user intervention, simple to use. Can be flexibly set the module parameters via software or microcontroller commands. 2.54 standard pin interface, easy embedded installation, TTL level signals. Built-in watchdog to ensure long-term reliable and stable operation. Open ground between nodes effective communication distance up to 2-3 km.
