M.2 Accelerator datasheet Version 1.5 Features Google Edge TPU ML accelerator 4 TOPS total peak performance (int8) 2 TOPS per watt Integrated power management PCIe Gen2 x1 interface Available in two M.2 form factors: M.2-2230-A-E-S3 (A+E key) M.2-2280-B-M-S3 (B+M key) Operating temp: -20 to +85 C Description The Coral M.2 Accelerator is an M.2 module (either A +E or B+M key) that brings the Edge TPU ML accelerator to existing systems and products. The Edge TPU is a small ASIC designed by Google that accelerates TensorFlow Lite models in a power ecient manner: it s capable of performing 4 trillion operations per second (4 TOPS), using 2 watts of powerthat s 2 T OPS per watt. For example, one Edge TPU can execute state-of-the-art mobile vision models such as MobileNet v2 at almost 400 frames per second. This on-device ML processing reduces latency, increases data privacy, and removes the n eed for a constant internet c onnection. The M.2 form-factor allows you to add local ML acceleration to p roducts such as embedded platforms, mini-PCs, and industrial gateways that have a compatible M.2 card slot.
