Coral Dev Board Mini is a compact edge AI platform featuring the Google Edge TPU coprocessor and Cortex-M7 CPU. It’s ideal for running TensorFlow Lite ML models in robotics, such as face/gesture detection or path planning.
Product Description
The Coral Dev Board Mini is a compact, cost-effective single-board computer built for high-performance on-device machine learning. Powered by the MediaTek 8167s SoC and Google's Edge TPU co-processor, it delivers up to 4 TOPS of AI acceleration while maintaining low power consumption. The board comes equipped with 2GB of LPDDR3 RAM, 8GB of eMMC storage, and built-in Wi-Fi and Bluetooth, making it ideal for embedded AI applications where latency, privacy, and offline functionality are key. Designed for rapid prototyping and deployment of edge AI models using TensorFlow Lite, it includes rich I/O options such as USB-C, micro HDMI, audio interfaces, camera/display connectors, and a 40-pin GPIO header. With its small form factor and support for Mendel Linux, the Coral Dev Board Mini offers a powerful, flexible platform for developers bringing AI inference to the edge. Key Features
- Equipped with a dedicated Edge TPU, the board delivers up to 4 TOPS (tera-operations per second), offering roughly 2 TOPS per watt, making it notably energy-efficient. For example, it can run models like MobileNet V2 at speeds approaching 400 frames per second.
- Quad‑core ARM Cortex‑A35 CPU (up to 1.5 GHz)
- Imagination PowerVR GE8300 GPU (supports Vulkan, OpenCL)
- 8 GB eMMC flash storage (pre‑flashed with Mendel Linux, a Debian derivative)
- 24‑pin MIPI‑CSI camera interface (up to 8 MP)
- On‑board cryptochip (A71CH) for establishing a root of trust
- Supports AutoML Vision Edge, for creating and deploying custom image classification models
- Ships with Mendel Linux (Debian‑based), ready to run
- Power requirements: 5 V / 2 A USB‑C; typical consumption peaks around 3 W, can be higher during heavy TPU usage
