Google remains as the forefront of tech development. Google offers an Edge Tensor Processing Unit (TPU) board as well as Edge TPU Accelerator. Its Edge TPU Accelerator is a USB device which works with boards such as the Raspberry Pi. Using Google's Edge TPU Accelerator, developers can harness low-power single-board computers (SBCs) such as the Pi and Odroid XU4 for various do-it-yourself (DIY) artificial intelligence (AI) projects. These chips are optimized for Google's TensorFlow machine learning framework, and for interfacing with edge devices.
