Adafruit has this week unveiled a new addition to their range of programmable micro-controller boards with the launch of the new NETduino 3 WiFi board, now in stock and ready for enthusiasts and developers. This new board can be programmed using the versatile and powerful Netduino platform.
To re-cap, NETduino is an open-source electronics platform that leverages the .NET Micro Framework. This framework allows developers to write code in C# and other .NET languages, making it accessible for those familiar with Microsoft’s development environment. The latest board is equipped with a 32-bit micro-controller and supports SSL/TLS 1.2 and WPA2, ensuring secure communications and robust performance.
Enhanced Specifications and Capabilities
The new NETduino 3 WiFi board boasts significant improvements over its predecessors. It features the same 168 MHz (Cortex-M4) processor as the Plus 2 but offers almost four times the code storage at 1408 KB and nearly double the RAM at 164+ KB. These enhancements provide developers with more space and flexibility to create complex and feature-rich applications.
The board’s wireless capabilities are a standout feature, enabling seamless integration into IoT projects. It supports most Arduino shields, although some may require .NET Micro Framework drivers. This compatibility ensures that developers can leverage existing hardware and expand their projects without starting from scratch.
Additional Features and Practical Applications
The NETduino 3 WiFi board also includes six 12-bit ADC channels, allowing for precise analog-to-digital conversions. This feature is particularly useful for applications requiring accurate sensor readings, such as environmental monitoring or robotics. Additionally, the board supports microSD card storage up to 2GB, providing ample space for data logging and other storage-intensive tasks.
Another notable feature is the inclusion of three GoBus ports. GoBus is a plug-and-play peripheral bus designed to simplify the connection of various modules and sensors. This makes it easier for developers to expand their projects with additional functionality without dealing with complex wiring and configuration.
The Adafruit online store is now stocking the NETduino 3 WiFi board, priced at $70. This competitive price point makes it an attractive option for hobbyists, educators, and professionals looking to develop IoT solutions or other embedded systems.
Real-World Applications and Use Cases
The NETduino 3 WiFi board’s robust feature set makes it suitable for a wide range of applications. For instance, in home automation, the board can be used to control lighting, heating, and security systems remotely. Its secure communication capabilities ensure that these systems remain protected from unauthorized access.
In educational settings, the NETduino 3 WiFi board serves as an excellent tool for teaching programming and electronics. Its compatibility with the .NET Micro Framework allows students to apply their knowledge of C# and other .NET languages in a practical, hands-on environment.
For industrial applications, the board’s reliable performance and extensive I/O options make it ideal for monitoring and controlling machinery, collecting data from various sensors, and integrating with other industrial systems.
In summary, the NETduino 3 WiFi board is a versatile and powerful addition to the Adafruit lineup. Its enhanced specifications, wireless capabilities, and broad compatibility make it a valuable tool for developers across various fields. Whether you’re working on a personal project, teaching a class, or developing a commercial product, the NETduino 3 WiFi board offers the features and flexibility you need to succeed.
