USB Edge TPU ML Accelerator coprocessor for Raspberry Pi and Other Embedded Single Board Computers

Purchased this device from this seller after a previous order from a different seller arrived DOA. Although slightly more expensive, device arrived quickly and haven't had any issues. Using it with Frigate running in a VM on a NUC 12 Pro with 4 cameras. Device works great and performs as promised, reducing CPU usage in the NUC significantly. Would highly recommend it for this purpose.Getting the device flashed, configured, and passing through to the VM is a little tricky and outside of the scope of this review, but for others who intend to use it that way, search for William Lam's guides on this. They're very detailed, easy to follow, and will get you up and running quickly.

I’ve been running the Google Coral USB Accelerator as part of my self-hosted Home Assistant and Frigate setup in my home lab, and it’s been a solid upgrade.My cameras stream through it for real-time object detection, and while the AI recognition isn’t perfect, it’s definitely good enough for home security and smart automation triggers.It picks up people, cars, and even the occasional animal (cats 🐱) with decent accuracy, and it’s responsive enough for live notifications or actions.The biggest win is offloading the CPU.Before Coral, my server was getting hammered by the detection workload, especially with multiple cameras running.Now, it’s smooth, CPU usage is way down, and the system feels a lot more stable and responsive. If you’re running Frigate or anything TensorFlow-based in a home setup, the Coral USB is a no-brainer.It’s compact, plug-and-play with a bit of config, and does exactly what it’s meant to.Note that the unit get pretty hot while working, this is normal.

This is an amazing and beastly device. If you know you know. It outperforms stacked RTX 1080s like it's child's play.I use this for a Frigate NVR that does detection on 5 camera feeds. Works great and never gets anywhere near capacity. I have it plugged into a rack server with USB 2.0 and it's fine. Probably would be superior with USB 3.Just plug it in and then follow the website. For debian it was a simple repo and package install. That's it. Ready to use. Don't even need to reboot of course yay Linux.If you use it for a Frigate setup maybe keep a light video card like a 2GB Nvidia to use for the movement detection in Frigate (instead of CPU) and use this TPU for object detection. You'll be amazed at the speed increase.

I had lots of hope for this... it would have been great to have a self contained TPU solution that can provide an assist to classification and detection tasks which I normally do with OpenCV on either a CISC or GPU right now.In comes Coral. The promise of fast tensor operations using a lower power dongle can't be beat.Now comes the bad: first, good luck finding this for the MSRP. Either production is low, or scalpers are having a field day on this. So, from the get-go you're paying 10-20% premium on the device.Next, if you get your hands on it, good luck trying to get it working with anything. Lots of the reviewers like this because they utilize it with Frigate which is cool. A+ for that workload...Now if you want to use it with anything else, there are some examples... and that's where things hit a bumpy road. Check out any of the Github repositories that are posted. Most were posted 3 or 4 years ago and have been untouched since... so trying bringing down an example and getting it to work... Windows examples don't work... WSL doesn't work... a recent version or LTS on Ubuntu... and same thing... nothing works. Good luck getting a response from the support address.So... summary: this thing is great if you have Frigate and need to increase camera counts without buying more cores or GPUs. It may be great if you can get it running on a RPi and do things that are simply not possible, there... but for CV applications... getting this to run will be the long tent pole due to the poorly maintained examples and stale support repositories making it a better move to just skip over this and go with a GPU solution such as a CUDA accelerated OpenCV approach or Deepstacks or anything else for that matter.If anything changes and I get this thing functional, I'll update this review accordingly.

The Google Coral USB Edge TPU ML Accelerator has been a game-changer for my home security setup. I've integrated it with Frigate to handle image processing from my security cameras, specifically for person detection. This setup, combined with Home Assistant, offers me an added layer of security without the need to lean on cloud services. The device itself is surprisingly compact, which was unexpected. On the downside, while I've noticed the price dropping a bit, it's still higher than what it was a couple of years ago. Nonetheless, for the peace of mind and local processing power it offers, it's been a worthy addition to my tech arsenal.

We have found the Google Coral, not just the USB accelerator, but all of their devices (USB version, Coral Deb Board and Env Sensing board), to be excellent. In fact, the performance is so high, and the parts so small, I was in technological amazement. The API docs, and the demos are quite easy to run, and give anyone a very easy way to quickstart.The only downside we encountered, at all, was the heat was pretty intense, but for what it does, and its tiny size, we just put some fans around it and it was WELL worth it.

Very good daytime detections for video processing. Little pricey but saves on power consumption which in the long run will make the coral rather cost effective.Absolutely terrible nighttime detection in the default model that's in used in most NVRs. With this having tiny amounts of onboard memory it's hard to run a decent model.

Got this for my Frigate server to help take the load off the cpu. The usb connection works with any computer with a USB port giving your motion capture and detection a boost.
