Introduction
Create a private IoT network for under $100. No cloud fees, full data privacy.
The DFRobot LoRaWAN Indoor Gateway (US915) is a comprehensive solution for home automation enthusiasts and IoT developers. Unlike traditional gateways that rely on external clouds, this device features a Built-in SIoT Local Server and Pre-installed Node-RED. Powered by a Quad-core Cortex-A35 processor and the high-performance Semtech SX1302 8-channel chip, it enables data collection from outdoor sensors (up to 4km range) with local processing. This architecture ensures data safety, facilitates home automation, and eliminates monthly subscription costs.

LoRaWAN Gateway Local Server - Privacy, Speed, and Reliability.
Most gateways act as simple bridges to the internet. The DFRobot Gateway operates as a standalone processing unit.
Total Privacy: Camera feeds, moisture levels, and location data never leave the local network.
Zero Latency: Local processing ensures instant response times for automations.
No Cloud Fees: Eliminates subscription services for data hosting.
Offline Operation: Smart garden or security systems continue functioning even without an internet connection.

Automate with Built-in Node-RED
Zero-Code Logic for Everyone. Building complex IoT systems does not require programming expertise. The industry-standard visual programming tool, Node-RED, comes pre-installed on the device.
Scenario: Smart Irrigation
Hardware: Gateway + Control Terminal
Logic: Connect a soil sensor to the Terminal's RS485/Analog port. Connect a water valve to the Relay port.
Node-RED Flow: Configure the Gateway to read sensor data -> If moisture < 20% -> Send Downlink command to open Relay.

High-Performance Hardware
Semtech SX1302 8-Channel Chip: Handles dozens of sensors simultaneously with high sensitivity (-140dBm).
Quad-Core CPU: Powerful Cortex-A35 processor (1.3GHz) ensures Node-RED flows run smoothly without lag.
Auto Data Parsing: Automatically converts raw hex data into readable values (e.g., converting 0x1C to 28°C).
DFRobot LoRaWAN Series
DFRobot LoRaWAN product series is centered on "simplified development and efficient deployment", covering scenarios such as learning, development, testing, and deployment, and providing developers with comprehensive low-power wide-area network (LPWAN) solutions.
Gateway: Embedded local MQTT server (SIoT) eliminates the need for server setup; supports Node-RED graphical programming for rapid automation task construction.
Control Terminal: Multi-interface design (analog/digital input, RS485, relays) enables both data acquisition and device control; supports custom control rules and stable offline operation without network connectivity.
Development Board: Compatible with the Arduino ecosystem, providing pre-built libraries and sample code for a low-threshold getting started; integrated with a screen, buttons, and other peripherals for real-time debugging without external devices.
Node Module: Built-in LoRa/LoRaWAN protocol stack, supporting multi-platform graphical programming; features standard I2C/UART interfaces, compatible with mainstream controllers such as Micro:bit, Arduino, and ESP32
