MCDODO

MCDODO Coral M.2 Accelerator A+E Key development board

SKU CH-QBRH-6NTK5

Performs high-speed ML inferencing at 400 FPS using 0.5 watts per TOPS on Debian Linux with TensorFlow Lite and AutoML Vision Edge support

  • Product typeSingle Board Computers
  • High-speed ML inferencing at 4 TOPS using 0.5 watts per TOPS
  • Executes MobileNet v2 at 400 FPS for real-time vision tasks
  • Runs TensorFlow Lite models directly on the Edge TPU coprocessor
  • Builds custom image classifiers with AutoML Vision Edge support
  • Integrates with any Debian-based Linux system via M.2 A+E key slot

High-speed ML inferencing board

The Coral M.2 Accelerator A+E Key adds an Edge TPU coprocessor to any Debian-based Linux system with a compatible M.2 slot. It delivers 4 trillion operations per second while consuming only 0.5 watts per TOPS. Developers can run mobile vision models such as MobileNet v2 at 400 FPS in a power-efficient manner. This board targets makers and engineers building edge AI prototypes.

4 TOPS at 2 TOPS per watt

The accelerator handles TensorFlow Lite models compiled for the Edge TPU and supports AutoML Vision Edge for custom image classification. It runs efficiently on 0.5 watts per TOPS, making it suitable for battery-powered or thermally constrained devices. Workloads requiring higher throughput or different model frameworks will exceed the capabilities of this single coprocessor. Systems without a compatible A+E key M.2 slot cannot use the board.

Debian Linux and TensorFlow Lite integration

The board works with any Debian-based Linux distribution that exposes a compatible M.2 A+E key slot, removing the need for proprietary operating systems. TensorFlow Lite models compile directly for the Edge TPU without rebuilding from scratch. AutoML Vision Edge lets users train and deploy custom image classifiers through a cloud workflow. No additional software licences or bundled development tools are included with the hardware.

Questions about this item

Will the Coral M.2 Accelerator fit in the A+E key slot on my existing single-board computer?

Yes, the board uses an A+E key M.2 interface, so it installs directly into any compatible slot on a Debian-based Linux system.

How can I verify the Edge TPU is running at the rated 4 TOPS after installation?

Run a TensorFlow Lite benchmark such as MobileNet v2; the coprocessor should deliver around 400 FPS at 0.5 watts per TOPS.

Does the package include a heatsink or mounting screws, or must I source them separately?

The board ships as a bare M.2 module; thermal pads, heatsinks and mounting hardware are not included and must be purchased separately.
