The Coral PoE Add-on Board is accessory board that adds ethernet power and connectivity to the Dev Board Micro. It simply snaps onto the Dev Board Micro with a high-density connector. Techical Specifications Ethernet Speed: 10 and 100 Mbps Max Power: 7 W continuous max power over Ethernet (shared with main board and any peripherals) Dimensions: 65.0 x 30.0 x 23.9 mm Requires the Coral Dev Board Micro for operation (sold separately).

The Google coral mini PCIe accelerator is a PCIe module that bring the edge TPU coprocessor to existing systems and product. It provide high performance ML inferencing with low power requirements. it's capable of performing 4 trillion operations per second. It used standard half-mini PCIe cardIt support debian Linux and other variants on host CPU

Benefits of the Coral Dev Board Micro The Coral Dev Board Micro is a microcontroller board that benefits from a built-in camera,microphone, and Coral Edge TPU, allowing you to quickly prototype and deploy low-power embedded systems with on-device ML inferencing. By combining the Cortex M4 and M7 processors with the Coral Edge TPU on this board, you can design systems that cascade from extreme low-power ML inferencing to more complex—yet still power-efficient—ML inferencing. You can also expand the hardware with custom add-on boards using the high-density board-to-board connectors. The Edge TPU is a small ASIC designed by Google that accelerates tensor flow lite models in a power efficient manner. One Edge TPU is capable of performing 4 trillion operations per second. This on-device ML processing reduces latency, increases data privacy, and removes the need for a constant internet connection.
