Entertainment
Introduction
In this article, we will explore the setup and functionality of the new Raspberry Pi AI Kit, which can significantly enhance the Raspberry Pi's capabilities in AI processing. This follows our previous two videos where we set up the Raspberry Pi 5 and explored the Raspberry Pi AI camera.
Setting Up the Raspberry Pi
Before diving into the AI Kit, it is essential to ensure that our Raspberry Pi is updated and configured correctly. In our first video, we set up the Raspberry Pi 5 and attached an active cooler to maintain operating temperatures. We also installed and configured Raspberry Pi OS.
In the second video, we examined the Raspberry Pi AI camera, which allows the offloading of neural networks for processing tasks such as object detection. The camera is capable of sending tensor data back to the Raspberry Pi, freeing it for further computations.
Introducing the Raspberry Pi AI Kit
The AI Kit is based on the M2 form factor and incorporates a Neural Processing Unit (NPU) capable of executing approximately 13 TOPS (Tera Operations Per Second) of AI tasks. This powerful processor enhances the AI capabilities of the Raspberry Pi, making it suitable for various applications.
The AI Kit connects to the Raspberry Pi via a PCIe connector through a ribbon cable and requires a proper fit on top of the device using GPIO pins and standoffs. The installation involves the following steps:
Unboxing and Assembly: In this segment, we unpack the AI Kit, which comes with all necessary components, including standoffs and an extension block for GPIO pins. There is also an M2 hat containing the Halo NPU, which is critical for the AI processing tasks.
Fitting the AI Kit: The assembly includes connecting the PCIe cable securely to ensure it is seated correctly. We also need to mount the AI Kit using the provided screws and standoffs, ensuring all components are properly in place.
Connecting the Camera: The Raspberry Pi AI Kit can work with various versions of the Raspberry Pi camera. For this setup, we are using the V2 camera and connecting it to the appropriate CSI port on the Raspberry Pi.
Software Configuration: After physically installing the AI Kit, we must ensure that the Raspberry Pi is using the latest firmware and that the PCIe is configured for optimal performance. This setup is performed using terminal commands.
Testing the AI Kit
Once everything is set up, we can verify the installation. We utilize commands to check the status of the Halo NPU, confirming that it is correctly identified and operational. The camera is tested by running the rpy_cam hello command to ensure it is functioning smoothly.
Next, we explore various demos available for the AI Kit. These demos showcase the capabilities of the AI Kit in object detection, image segmentation, and pose estimation, using different neural network models like YOLO V5, YOLO V8, and others. Each model has distinct strengths for detecting various objects, highlighting the flexibility of the AI Kit.
By running these demos, we demonstrate the AI Kit's ability to identify and segment objects in real time, showcasing its practical application in AI-powered projects.
Conclusion
Through this series, we've seen how the Raspberry Pi can be transformed into a powerful AI processing unit. The AI Kit enhances its functionality and opens doors for advanced projects using AI technologies. We encourage you to explore these capabilities further and experiment with different AI models available through the Halo resource library.
