Are Google Coral devices worthy to buy?

“Coral is a complete toolkit to build products with local AI. “—— Google.
Now google coral has 8 devices: Dev Board, USB Accelerator, Mini PCIe Accelerator, M.2 Accelerator A+E key, M.2 Accelerator B+M key, System-on-Module (SoM), Coral Camera, Environmental Sensor Board.
from prototype to production, coral devices make it easy to take your idea from sketch into proof-of-concept.
Coral provides a complete platform for accelerating neural networks on embedded devices. At the heart of our accelerators is the Edge TPU coprocessor. It's a small-yet-mighty, low-power ASIC that provides high performance neutral net inferencing.
Coral’s local AI technology enables new possibilities across almost any kind of industry: Building smarter cities, Making manufacturing work better, Helping people get around, Keeping people healthy and etc.
for example, Local AI provides high performance, offline analysis for agriculture challenges that can improve soil quality, plant health, and crop yield in order to produce more food, reduce environmental impact, and enable sustainable farming practices.

Beyond that, Google offers the Edge TPU in multiple form factors to suit various prototyping and production environments—from embedded systems deployed in the field, to network systems operating on-premise.
For example, the Coral USB Accelerator simply plugs into a desktop, laptop, or embedded system such as a Raspberry Pi so you can quickly prototype your application. From there, you can scale to production systems by adding our Mini PCIe or M.2 Accelerator to your hardware system.
If you're looking for a fully-integrated system, you can get started with Coral Dev Board—a single-board computer based on NXP's 8M system-on-chip. Then you can scale to production by connecting our System-on-Module (included on the Dev Board) to your own baseboard.
so Google Coral is really worthy to buy, the price is nice to developers.

How to Retrain an object detection model

This tutorial shows you how to retrain an object detection model to recognize a new set of classes. You'll use a technique called transfer learning to retrain an existing model and then compile it to run on an Edge TPU device—you can use the retrained model with either the Coral Dev Board or the Coral USB Accelerator. Specifically, this tutorial shows you how to retrain a MobileNet V1 SSD model (originally trained to detect 90 objects from the COCO dataset) so that it detects two pets: Abyssinian cats and American Bulldogs (from the Oxford-IIIT Pets Dataset). But you can reuse these procedures with your own image dataset, and with a different pre-trained model. The steps below show you how to perform transfer-learning using either last-layers-only or full-model retraining. Most of the steps are the same; just keep an eye out for the different commands depending on the technique you desire. Note: These instructions do not require deep experience with TensorFlow o...

How to retrain an image classification model?

Got a tutorial from Google Coral Team: This tutorial shows you how to retrain an image classification model to recognize a new set of classes. You'll use a technique called transfer learning to retrain an existing model and then compile it to run on an Edge TPU device—you can use the retrained model with either the Coral Dev Board or the Coral USB Accelerator. Specifically, this tutorial shows you how to retrain a  quantized  MobileNet V1 model to recognize different types of flowers (adopted from TensorFlow's docs). But you can reuse these procedures with your own image dataset, and with a different pre-trained model. Tip:  If you want a shortcut to train an image classification model, try Cloud AutoML Vision. It's a web-based tool that allows you to train a model with your own images, optimize it, and then export it for the Edge TPU. Set up the Docker container Prepare your dataset Retrain your classification model Compile the model for the Edge TPU Run...
