seeed studio Google Coral USB Accelerator

Unlike other USB sticks (like the Intel NCS2) this will only run TF Lite, nothing else.Works well for inference (cannot strictly train on this except under limited circumstances i.e. the FC/Dense layers in a model, all other weights must be frozen).If you are looking at developing for upcoming Android platform ASIC's (on a phone for instance) this is an ideal test device to make sure your models are ready and deployable. Believe folk buy for the Raspberry Pi... never had one but from what I hear very good for this as well.Very small and light, took me 20 minutes from unboxing to running inference demos under Ubuntu 19.04.
