Description

This Elecrow module is a fully-integrated, single-channel LoRaWAN gateway solution designed for developers and system integrators needing a compact, programmable bridge between LoRa end-devices and cloud networks. At its core is the ESP32-WROOM-32, handling packet forwarding, network stack management, and the local UI on the integrated display. The RA-01H LoRa transceiver provides the physical layer link, operating in the 868MHz EU band with configurable spreading factors and data rates.

Power management is handled via the USB-C input, supporting a wide voltage range for field deployment. The inclusion of both WiFi and wired Ethernet offers critical redundancy for the gateway’s backhaul connection to The Things Network or private LoRaWAN servers. The acrylic enclosure protects the board while providing mounting points, making it suitable for prototyping and small-scale IoT deployments in smart agriculture, environmental monitoring, and asset tracking scenarios.

Key Features

  • Single-channel LoRaWAN 1.0.3 gateway compatible with The Things Network (TTN) and other standard servers.
  • ESP32-WROOM-32 dual-core LX6 processor (240 MHz) enables complex gateway applications and local data processing.
  • On-board 1.8" ST7735S-driven TFT LCD provides immediate visual feedback for status, RSSI, and packet counts.
  • Flexible IP connectivity via 2.4GHz WiFi and 10/100 Mbps Ethernet (RJ45 with built-in PHY).
  • USB-C interface for both 5V power supply and serial communication for programming and debugging.
  • Pre-assembled acrylic case offers mechanical protection and simplified mounting for indoor installations.
  • Dedicated antenna connectors for both LoRa (SMA) and WiFi (IPEX) ensure optimal RF performance.
  • Fully programmable with Arduino IDE and MicroPython, allowing for custom packet forwarding rules and data handling.

Applications

  • Prototype and small-scale LoRaWAN network gateways for The Things Network (TTN).
  • Remote environmental monitoring stations collecting sensor data (temperature, humidity, air quality).
  • Smart agriculture systems for soil moisture, irrigation control, and livestock tracking.
  • Urban IoT deployments for smart parking, waste management, and asset tracking.
  • Educational and research platforms for wireless communication and IoT protocol studies.

Frequently Asked Questions

How do I connect this gateway to The Things Network (TTN)?

First, create an application and gateway on the TTN Console to obtain a Gateway ID and key. Then, using the Arduino IDE with the ESP32 board package installed, load a gateway sketch (like the TTN Single Channel Gateway example). Configure the sketch with your WiFi/Ethernet credentials, TTN Gateway ID, and frequency plan (EU868). Upload via USB-C, and the gateway will connect to TTN and begin forwarding LoRaWAN packets from end devices.

What is the purpose of the 1.8" LCD screen, and how do I program it?

The LCD displays real-time gateway status such as IP address, connected LoRaWAN server, RSSI of received packets, packet counters, and any system errors. It uses an ST7735S driver connected via SPI. To program it, include a TFT library like TFT_eSPI in your Arduino sketch. Define the correct pins (defined in the board's pinout) and use library functions to draw text and graphics, updating the display with live data from the gateway operation.

Can I power this gateway remotely, and what are the power requirements?

Yes, the gateway is powered solely via its USB-C port, requiring a stable 5V DC supply. For remote deployment, you can use a 5V USB power adapter connected to mains or a solar/battery system with a 5V regulator. The active current draw is typically between 300-500 mA when both LoRa and WiFi/Ethernet are active. Ensure your power source can provide at least 1A for stable operation, especially if using the display and both radios simultaneously.

How do I switch between using WiFi and Ethernet for the backhaul connection?

The gateway firmware (e.g., the TTN gateway code) typically prioritizes Ethernet if a cable is detected and linked; otherwise, it falls back to WiFi. You must configure credentials for both in your sketch. For WiFi, set the SSID and password. For Ethernet, the PHY is auto-detected, but you may need to enable DHCP or set a static IP. The system handles the network stack, but you should verify connectivity by checking the assigned IP on the LCD or via serial monitor after boot.
