Coral G650-07968-01, Dev Board Micro ARM Cortex Microcontroller Board
The Coral G650-07968-01 Dev Board Micro is a compact development board designed for embedded systems, machine learning, and edge AI applications. Powered by the NXP i.MX RT1176 microcontroller and a Coral Edge TPU coprocessor, it enables developers to build intelligent devices that process data locally without relying entirely on cloud-based computing.
Featuring dual Arm Cortex-M7 and Cortex-M4 cores, the board supports a range of embedded computing tasks, from real-time control to sensor data processing. Its support for TensorFlow Lite for Microcontrollers makes it suitable for developing machine learning applications in resource-constrained environments, including smart sensors, connected devices, and intelligent control systems.
The integrated Coral Edge TPU accelerator delivers up to 4 trillion operations per second (TOPS) for high-performance inference with TensorFlow Lite models. This capability helps developers implement applications such as image recognition, object detection, and other supported machine learning tasks directly on the device, enabling responsive processing with reduced dependence on external computing resources.
With an onboard Himax HM01B0 camera sensor, a mono microphone, and multiple hardware connection options, the Dev Board Micro supports prototyping for vision-based and audio-enabled applications. Its GPIO headers and board-to-board connectors provide interfaces for connecting peripherals, sensors, and compatible expansion boards, making it useful for robotics, automation, and embedded product development.
The compact design, onboard memory, secure element, and USB-C connectivity make the Coral G650-07968-01 suitable for developers, engineers, and researchers building space-constrained intelligent devices. It provides a practical platform for experimenting with embedded machine learning, sensor integration, and edge inference in applications where size and local processing capabilities are important.
