Google Coral Dev Board (4GB) [discontinued]
A development board to quickly prototype on-device ML products. Scale from prototype to production with a removable system-on-module (SoM).
The Google Coral Dev Board 4GB is a single-board computer that’s ideal when you need to perform fast machine learning (ML) inferencing in a small form factor. You can use the Dev Board to prototype your embedded system and then scale to production using the onboard Coral System-on-Module (SoM) combined with your custom PCB hardware.
A camera module designed specifically for the Google Coral range is available here.
Performs high-speed ML inferencing
The on-board Edge TPU coprocessor is capable of performing 4 trillion operations (tera-operations) per second (TOPS), using 0.5 watts for each TOPS (2 TOPS per watt). For example, it can execute state-of-the-art mobile vision models such as MobileNet v2 at almost 400 FPS, in a power efficient manner. See more performance benchmarks.
Provides a complete system
A single-board computer with SoC + ML + wireless connectivity, all on the board running a derivative of Debian Linux we call Mendel, so you can run your favourite Linux tools with this board.
Supports TensorFlow Lite
No need to build models from the ground up. TensorFlow Lite models can be compiled to run on the Edge TPU.
Supports AutoML Vision Edge
Easily build and deploy fast, high-accuracy custom image classification models to your device with AutoML Vision Edge.
Scale from prototype to production
Considers your manufacturing needs. The SoM can be removed from the baseboard, ordered in bulk, and integrated into your hardware.
Additional 1GB SOM available here.
