Coral Dev Board

The Coral Dev Board is a single-board computer with a removable system-on-module (SOM) that contains eMMC, SOC, wireless radios, and Google’s Edge TPU. It’s perfect for IoT devices and other embedded systems that demand fast on-device ML inferencing.

You can use the Dev Board as a single-board computer for accelerated ML processing in a small form factor, or as an evaluation kit for the SOM that’s on-board. The 40 mm × 48 mm SOM on the Dev Board is available at volume. It can be combined with your custom PCB hardware using board-to-board connectors for integration into products.

The SOM is based on NXP's iMX8M system-on-chip (SOC), but its unique power comes from the Edge TPU coprocessor. The Edge TPU is a small ASIC designed by Google that provides high performance ML inferencing with a low power cost. For example, it can execute state-of-the-art mobile vision models such as MobileNet v2 at 100+ fps, in a power efficient manner. 

Edge TPU key benefits

• High-speed TensorFlow Lite inferencing
• Low Power
• Small footprint

The baseboard includes all the peripheral connections you need to prototype a project, including USB 2.0/3.0 ports, DSI display interface, CSI2 camera interface, Ethernet port, speaker terminals, and a 40-pin GPIO header.  

Coral is a division of Google, that helps you build intelligent ideas with our platform for local AI.

Gigabit Ethernet ports

40-pin GPIO expansion headers

Supports Debian Linuxs

Models are built using TensorFlow  

Fully supports MobileNet and Inception architectures though custom architectures are possible  

Compatible with Google Cloud

Supports TFLite

No need to build models from the ground up. TensorFlow Lite models can be compiled to run on the Coral Dev Board. 

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.

Includes a full system

SOC + ML + Connectivity all on the board running a variant of Linux, so you can run your favourite Linux tools with this board.
