4. Setup Instructions
This chassis is designed to integrate with the Seeed Wio Terminal development board. Follow these steps for initial setup:
- Prepare Components: Ensure you have the Wio Terminal LoRaWAN Chassis, the included antenna, and a Seeed Wio Terminal development board. Optionally, a Wio Terminal Battery Chassis can be used for portable applications.
- Attach Antenna: Carefully screw the provided antenna onto the SMA connector located on the side of the LoRaWAN Chassis. Ensure it is finger-tight but do not overtighten.
- Insert Wio Terminal: Align the 40-pin male headers of the Wio Terminal LoRaWAN Chassis with the corresponding female headers on your Wio Terminal. Gently press the Wio Terminal into place until it is securely seated.
- Power On: Connect your Wio Terminal to a power source (e.g., USB-C cable) or ensure the optional battery chassis is powered.


5. Operating Instructions
Operating the Wio Terminal LoRaWAN Chassis involves programming the Wio Terminal to utilize the integrated LoRa-E5 and GNSS modules. This typically requires an understanding of Arduino programming and LoRaWAN protocols.
5.1. Software Setup
- Install Arduino IDE: Ensure you have the Arduino IDE installed on your computer.
- Install Wio Terminal Board Support: Add the Seeed Wio Terminal board support package to your Arduino IDE.
- Install Libraries: Install necessary libraries for LoRaWAN communication (e.g., LoRaWAN library for LoRa-E5) and GNSS module (e.g., TinyGPS++ or similar for Quectel L76-LB). Refer to the official Seeed Studio documentation for specific library recommendations and installation guides.
5.2. Programming and Communication
- LoRaWAN Communication: The LoRa-E5 module supports LoRaWAN protocol and AT commands. You can program the Wio Terminal to send and receive data over a LoRaWAN network. This involves configuring device EUI, application EUI, and application key for network registration.
- GNSS Data Acquisition: The Quectel L76-LB GNSS module provides GPS, GLONASS, and BeiDou positioning data. You can access this data via serial communication from the Wio Terminal to obtain latitude, longitude, altitude, time, and satellite information.
- Example Projects: Seeed Studio provides example projects such as the "WioTerminal LoRaWAN Network Analyzer" and "IoT Smart Garden Monitor" which can serve as starting points for your own applications. These projects demonstrate how to interface with the LoRa-E5 and GNSS modules.
6. User Tips
- Antenna Placement: For optimal LoRaWAN performance, ensure the antenna is positioned vertically and has a clear line of sight, especially for long-distance transmissions.
- Power Management: When running battery-powered applications, optimize your code for low-power consumption, utilizing the ultra-low-power design features of the LoRa-E5 module.
- GNSS Signal: For accurate GNSS readings, operate the device outdoors with an unobstructed view of the sky. Initial satellite acquisition may take a few minutes.
- Firmware Updates: Regularly check the Seeed Studio website for firmware updates for the LoRa-E5 module and Wio Terminal, as these can improve performance and add new features.
- Community Support: Engage with the Seeed Studio community forums for project ideas, troubleshooting, and sharing knowledge with other users.
