"I plugged this B+M key Edge TPU into my motherboard's (Asrock B650m) M-slot and it worked.Installed drivers was a bit of a hassle on Debian, but that's not a reflection of the purchase.Works as advertised, and pulls all the AI detection away from my CPU without breaking a sweat."

For what it is meant for it is very impressive. I set mine up currently for low-res image detection with frigate running in a Docker container via an Arch Linux host. It performs detections in I believe 6ms or so for me.m

I added this card to my frigate server as the CPU was not able to handle object detection very well. After adding this card and getting things setup properly, my frigate is much more stable and the CPU hardly takes a hit.nuck

I was looking for alternatives for hosting my own cameras with an AI for object detection. I wanted a small form factor PC instead of having to rely on old gaming PCs with a graphics card to heat up my closet. I ran across this, and decided to try it in an HP Elite Desk Mini 800 G5. It has two NVME slots as well as the WiFi/Bluetooth slot. I had hoped to use the other Coral M.2 with two TPUs, but my WiFi slot wasn't fast enough. I went with this version that fits in my second NVME slot. It works great with CodeProject AI. CPU detection without this was over 400ms, added this and it was comparable to my full desktop with a GTX 970 at less than 60ms detection time. Sometimes even less than 20ms.sara
