If your project requires a LoRaWAN module DFRobot may have the solution you're looking for. DFRobot DFR1115 Gravity LoRaWAN Node Modules, available in both EU868 and US915 variants, are compact, easy-to-integrate wireless communication modules designed for long-distance, low-power Internet of Things (IoT) applications. Built on the Semtech SX1262 LoRa RF chip and supporting both LoRa point-to-point (P2P) and LoRaWAN networking, these DFRobot modules provide reliable, wide-area data transmission without the need for wired infrastructures. With a wide 1.5km communication range in urban areas and 4.5km in open environments, the DFR1115 modules are an ideal solution for agriculture, environmental monitoring, industrial sensing, and outdoor IoT networks. DFRobot DFR1115 modules support Class A and Class C LoRaWAN modes, compatible with platforms such as The Things Network (TTN) and ChirpStack, using either OTAA or ABP activation methods. Featuring integrated protocol stacks, onboard PCB antennas, and dual communication interfaces (UART and I2C), the modules require no low-level development and are fully compatible with Arduino, ESP32, micro:bit, and other 3.3V/5V development boards for rapid deployment. The ultra-low-power LoRa technology significantly extends battery life in field sensor nodes, while the plug-and-play Gravity interface ensures straightforward integration into existing systems.
