We’re committed to evolving Coral to make it even easier to build systems with on-device AI. Our team is constantly working on new product features, and content that helps ML practitioners, engineers, and prototypers create the next generation of hardware.
To improve our toolchain, we're making the Edge TPU Compiler available to users as a downloadable binary. The binary works on Debian-based Linux systems, allowing for better integration into custom workflows. Instructions on downloading and using the binary are on the Coral site.
We’re also adding a new section to the Coral site that showcases example projects you can build with your Coral board. For instance, Teachable Machine is a project that guides you through building a machine that can quickly learn to recognize new objects by re-training a vision classification model directly on your device. Minigo shows you how to create an implementation of AlphaGo Zero and run it on the Coral Dev Board or USB Accelerator.
Our distributor network is growing as well: Arrow will soon sell Coral products.

AI can be beneficial for everyone, especially when we all explore, learn, and build together. To that end, Google's been developing tools like TensorFlow and AutoML to ensure that everyone has access to build with AI. Today, we're expanding the ways that people can build out their ideas and products by introducing Coral into public beta.
Coral is a platform for building intelligent devices with local AI.
Coral offers a complete local AI toolkit that makes it easy to grow your ideas from prototype to production. It includes hardware components, software tools, and content that help you create, train and run neural networks (NNs) locally, on your device. Because we focus on accelerating NN's locally, our products offer speedy neural network performance and increased privacy — all in power-efficient packages. To help you bring your ideas to market, Coral components are designed for fast prototyping and easy scaling to production lines.
Our first hardware components feature the new Edge TPU, a small ASIC designed by Google that provides high-performance ML inferencing for low-power devices. For example, it can execute state-of-the-art mobile vision models such as MobileNet V2 at 100+ fps, in a power efficient manner.
Coral Camera Module, Dev Board and USB Accelerator
For new product development, the Coral Dev Board is a fully integrated system designed as a system on module (SoM) attached to a carrier board. The SoM brings the powerful NXP iMX8M SoC together with our Edge TPU coprocessor (as well as Wi-Fi, Bluetooth, RAM, and eMMC memory). To make prototyping computer vision applications easier, we also offer a Camera that connects to the Dev Board over a MIPI interface.
To add the Edge TPU to an existing design, the Coral USB Accelerator allows for easy integration into any Linux system (including Raspberry Pi boards) over USB 2.0 and 3.0. PCIe versions are coming soon, and will snap into M.2 or mini-PCIe expansion slots.
When you're ready to scale to production we offer the SOM from the Dev Board and PCIe versions of the Accelerator for volume purchase. To further support your integrations, we'll be releasing the baseboard schematics for those who want to build custom carrier boards.
Our software tools are based around TensorFlow and TensorFlow Lite. TF Lite models must be quantized and then compiled with our toolchain to run directly on the Edge TPU. To help get you started, we're sharing over a dozen pre-trained, pre-compiled models that work with Coral boards out of the box, as well as software tools to let you re-train them.
For those building connected devices with Coral, our products can be used with Google Cloud IoT. Google Cloud IoT combines cloud services with an on-device software stack to allow for managed edge computing with machine learning capabilities.
Coral products are available today, along with product documentation, datasheets and sample code at g.co/coral. We hope you try our products during this public beta, and look forward to sharing more with you at our official launch.

Over the past year and a half, we've seen more than 200K people build, modify, and create with our Voice Kit and Vision Kit products. Today at Cloud Next we announced two new devices to help professional engineers build new products with on-device machine learning(ML) at their core: the AIY Edge TPU Dev Board and the AIY Edge TPU Accelerator. Both are powered by Google's Edge TPU and represent our first steps towards expanding AIY into a platform for experimentation with on-device ML.
The Edge TPU is Google's purpose-built ASIC chip designed to run TensorFlow Lite ML models on your device. We've learned that performance-per-watt and performance-per-dollar are critical benchmarks when processing neural networks within a small footprint. The Edge TPU delivers both in a package that's smaller than the head of a penny. It can accelerate ML inferencing on device, or can pair with Google Cloud to create a full cloud-to-edge ML stack. In either configuration, by processing data directly on-device, a local ML accelerator increases privacy, removes the need for persistent connections, reduces latency, and allows for high performance using less power.
The AIY Edge TPU Dev Board is an all-in-one development board that allows you to prototype embedded systems that demand fast ML inferencing. The baseboard provides all the peripheral connections you need to effectively prototype your device — including a 40-pin GPIO header to integrate with various electrical components. The board also features a removable System-on-module (SOM) daughter board can be directly integrated into your own hardware once you're ready to scale.
The AIY Edge TPU Accelerator is a neural network coprocessor for your existing system. This small USB-C stick can connect to any Linux-based system to perform accelerated ML inferencing. The casing includes mounting holes for attachment to host boards such as a Raspberry Pi Zero or your custom device.
On-device ML is still in its early days, and we're excited to see how these two products can be applied to solve real world problems — such as increasing manufacturing equipment reliability, detecting quality control issues in products, tracking retail foot-traffic, building adaptive automotive sensing systems, and more applications that haven't been imagined yet.
Both devices will be available online this fall in the US with other countries to follow shortly.

Last year, AIY Projects launched to give makers the power to build AI into their projects with two do-it-yourself kits. We're seeing continued demand for the kits, especially from the STEM audience where parents and teachers alike have found the products to be great tools for the classroom. The changing nature of work in the future means students may have jobs that haven't yet been imagined, and we know that computer science skills, like analytical thinking and creative problem solving, will be crucial.
We're taking the first of many steps to help educators integrate AIY into STEM lesson plans and help prepare students for the challenges of the future by launching a new version of our AIY kits. The Voice Kit lets you build a voice controlled speaker, while the Vision Kit lets you build a camera that learns to recognize people and objects (check it out here). The new kits make getting started a little easier with clearer instructions, a new app and all the parts in one box.
To make setup easier, both kits have been redesigned to work with the new Raspberry Pi Zero WH, which comes included in the box, along with the USB connector cable and pre-provisioned SD card. Now users no longer need to download the software image and can get running faster. The updated AIY Vision Kit v1.1 also includes the Raspberry Pi Camera v2.

We're also introducing the AIY companion app for Android, available here in Google Play, to make wireless setup and configuration a snap. The kits still work with monitor, keyboard and mouse as an alternate path and we're working on iOS and Chrome companions which will be coming soon.
The AIY website has been refreshed with improved documentation, now easier for young makers to get started and learn as they build. It also includes a new AIY Models area, showcasing a collection of neural networks designed to work with AIY kits. While we've solved one barrier to entry for the STEM audience, we recognize that there are many other things that we can do to make our kits even more useful. We'll once again be at #MakerFaire events to gather feedback from our users and in June we'll be working with teachers from all over the world at the ISTE conference in Chicago.
The new AIY Voice Kit and Vision Kit have arrived at Target Stores and Target.com (US) this month and we're working to make them globally available through retailers worldwide. Sign up on our mailing list to be notified when our products become available.
We hope you'll pick up one of the new AIY kits and learn more about how to build your own smart devices. Be sure to share your recipes on Hackster.io and social media using #aiyprojects.
