• RF Output Power - Up to +27 dBm (High Power version)
• Receiver Sensitivity - Down to -152 dBm
• Communication Range - Up to 6,000 meters (6 km) line-of-sight
• Communication Protocols - LoRaWAN Class A & C, LoRa Point-to-Point (firmware dependent)
• Hardware Interfaces - UART, I²C, SPI, GPIO (Digital I/O and Analog Inputs)
• Operating Voltage - 3.3V to 5.5V
• Physical Dimensions - 36 × 30 mm metal-shielded module with a U.FL antenna connector
Core Features & Target Use Cases
• Integrated Front-End: Unlike standard modules, the "HP" variant incorporates a High-Power Low-Noise RF front-end to maximize link budget and punch through physical obstructions.
• On-Board Storage: Includes built-in EEPROM for non-volatile data storage (useful for storing network encryption keys and configuration state).
• Primary Deployments: It is primarily utilized in industrial IoT, smart metering (AMR), asset tracking, and environmental remote monitoring setups.
