Coral Development Board Mini

Coral Development Board Mini is a single-board computer that enables quick prototyping and deployment. With on-device machine learning (ML) inferencing, the Coral Development Board integrates the Edge TPU coprocessor into custom PCB hardware as a surface-mount module. The small 64mm x 48mm board can perform 4 trillion operations per second (TOPS).  Coral, Google’s platform for on-device AI, offers hardware components, software tools, and pre-compiled models for building intelligent devices.

The board runs on a derivative of Debian Linux called Mendel, so many Linux tools can run on the Coral Dev Board Mini. The board supports TensorFlow Lite, eliminating the need to build models from the ground up, and supports AutoML Vision Edge that allows high-accuracy custom image classification models.
