Coral Dev Board Micro

Coral Dev Board Micro is a microcontroller board with a built-in camera, microphone, and Coral Edge TPU. Quickly prototype and deploy low-power embedded systems with on-device ML inferencing. The board combines Cortex M4 and M7 processors with Coral Edge TPU. Design systems that gracefully cascade from extremely low-power ML inferencing to more complex power-efficient ML inferencing.
