A customer approached me about what our recommendation is for developing a product which has integrated AI capabilities, and their respective price points and long-term availabilities, and volume availabilities.
This is a commercial comparison of these platforms, in an easy to peruse table, including pricing information.

(for the Jetson Nano module)
Note: the Jetson Nano operates with floating point data for the model, vs. the Coral module, which operates with int8 quantized data for the model (e.g. weights). TOPs = trillion operations per second vs. GFLOPS = billion floating point operations per second. Operating with floating point data also allows to train models (albeit slowly on the Jetson Nano), vs. the Coral series which can only run models. There are other trade-offs, like power efficiency, etc.
For the Coral Devboard 4 GB, currently a new 4 GB RAM module is being evaluated – therefore it is not available ex stock.
If you need the lowest price point, or the lowest power usage, go with the Coral Devboard Micro.
Note, if you need network connectivity, and can use more power in your project, the Raspberry Pi 4/1GB and Coral USB combination is a better choice.
If you need an integrated and compact solution, the Coral Devboard 1 GB or 4 GB solutions might be a good choice, albeit at a higher price point than the Raspberry Pi equivalents. Also note, that Raspberry Pi OS has a much bigger community behind it than Mendel Linux.
If you need Floating Point operations to run your model (i.e. you can’t quantize it to int8 very well), or four USB 3.0 ports for your application, you can go with the Jetson Nano.
The Coral series also has a Devboard Mini product, which sits between the Devboard Micro and the Devboard 1 GB from a performance perspective. It offers built-in Wireless networking capabilities. The Coral TPU module is connected using USB 2.0, so performance is lower than on the Raspberry Pi or “full” Devboard platforms. One big advantage of this module is it’s very compact footprint.
