Gravity LoRaWAN Node Module EU868

The DFRobot Gravity LoRaWAN Node Module DFR1115-868 is a compact module for implementing LoRa and LoRaWAN nodes in the EU868 frequency range. It supports both LoRa P2P and LoRaWAN (Class A and C) and is suitable for IoT applications like environmental monitoring, agriculture, smart home or prototyping. Thanks to the integrated protocol stack, projects can be implemented without deep low-level knowledge. The module can be directly connected to microcontrollers like Arduino, ESP32, or other boards via I²C or UART. With its long range, low power consumption, and onboard antenna, the module is ideal for reliable wireless connections even over several kilometers.

Features:

• The module supports LoRa P2P and LoRaWAN Class A and C.
• It is based on the SX1262 chip with high range and sensitivity.
• The I²C and UART interfaces are selectable.
• Compatible with 3.3 V and 5 V logic levels.
• An onboard PCB antenna is already integrated.
• Development environments like Arduino IDE, Mind+ and MakeCode are supported.
• The radio range is several kilometers, depending on environment and antenna.

Examples of application:

• Monitoring environmental parameters in gardens or agriculture.
• Integration into smart home systems with LoRaWAN.
• Data transmission from weather stations or moisture sensors.
• IoT prototyping in education.
