Built around the Semtech SX1262 and LoRa modulation, it operates on the 915 MHz US915 band and supports both direct LoRa communication and LoRaWAN networking.It can be used for point-to-point links or connected into a LoRaWAN network through gateways and platforms such as TTN or ChirpStack. The module is suited to wide-area sensing where Wi-Fi or 4G may be unavailable or too power-hungry, with quoted performance of up to 1.5 km in urban settings and up to 4.5 km in open environments.Integration is kept straightforward with a built-in LoRa/LoRaWAN protocol stack, UART and I2C interfaces, and support for Arduino IDE, Mind+ and MakeCode graphical programming. It is compatible with popular controllers including micro:bit, Arduino and ESP32, and comes with a PH2.0-4P connection cable.Features:Dual communication modes: Supports both LoRa point-to-point communication and LoRaWAN networking.LoRa point-to-point: Supports one-to-one, one-to-many, many-to-one and bridge transmission.LoRaWAN classes: Supports LoRaWAN Class A and Class C.Gateway integration: Can integrate with cloud platforms like TTN or ChirpStack via LoRaWAN gateways.Kilometre-range wireless: Up to 1.5 km in urban settings.Open-area range: Up to 4.5 km in open environments.Built-in protocol stack: Includes LoRa/LoRaWAN protocol support without low-level development.Arduino IDE support: Suitable for Arduino-based development.Mind+ support: Supports Mind+ programming.MakeCode support: Supports MakeCode graphical programming.Controller compatibility: Compatible with micro:bit, Arduino and ESP32.Included cable: PH2.0-4P connection cable included.Specifications:Operating Voltage: 3.3V to 5V DCCommunication Interfaces: UART and I2CConnector Type: PH2.0-4PLogic Level Compatibility: 3.3V / 5VBoard Dimensions: 42 × 62 mm (1.65 × 2.44 in)Mounting Hole Diameter: 3.0 mm (0.12 in)Mounting Hole Spacing: 35 mm (1.38 in)Net Weight: 10 g (0.35 oz)RF Chip: Semtech SX1262Operating Frequency: 915 MHzSupported Regions: North America and other regions using the US915 frequency bandModulation: LoRaSpreading Factor: SF7 to SF12Max Transmit Power: +22 dBmReceiver Sensitivity: -137 dBm (SF12 @ 125 kHz bandwidth)Typical applications include farm condition monitoring, greenhouse temperature and humidity sensing, beehive monitoring, ecological area data collection and LoRaWAN-enabled weather stations.","vendor":"DFRobot","product_type":"LoRaWAN Module","in_stock":true,"options":[],"variants":[{"id":15832,"title":"Default Title","sku":"DF-DFR1115-915","mpn":"DFR1115-915","price":24.05,"on_sale":false,"in_stock":true,"available_quantity":210}]}
