Features Google Edge TPU ML accelerator coprocessor USB 3.0 Type-C socket Supports Debian Linux on host CPU Overview The Coral USB Accelerator is a USB device that adds an Edge TPU coprocessor to your system. It includes a USB socket so you can connect it to any Linux-based system to perform accelerated ML inferencing. The on-board Edge TPU is a small ASIC designed by Google that provides high performance ML inferencing with a low power cost.
System requirements The Coral USB Accelerator must be connected to a host computer with the following specifications: Any Linux computer with a USB port Debian 6.0 or higher, or any derivative thereof (such as Ubuntu 10.0+) System architecture of either x86-64 or ARM32/64 with ARMv8 instruction set Components overview The Coral USB Accelerator is a small PCB that provides an Edge TPU coprocessor for your host CPU system.

Product dimensions Figure 1. Device dimensions and mounting hole details USB cable length: 300mm +/- 20 mm Software and operation The USB Accelerator doesn't require any software installed, but the host computer to which it's attached must install the Edge TPU runtime and API library. For instructions, see the Get Started guide. For information about how to create models and run inferences the Edge TPU, read TensorFlow models on the Edge TPU.
To change this setting, simply install the alternate runtime, as per the instructions to install the Edge TPU runtime. LED behavior The USB Accelerator includes an LED that lights up according to the current system state, as indicated in the following table. Table 2.
