## Come hack on chestnuts\![Permalink](https://blog.comma.ai/comma-hack-7/#come-hack-on-chestnuts "Permalink")

What does your embedded project look like with 172 TFLOPs? **[Chestnut](https://blog.comma.ai/chestnut/) is the easiest way to throw real GPU compute onto your embedded projects.**

Chestnut connects to any device with a USB port, all the way down to USB2. That means it works with your laptop, Raspberry Pi, comma four, and even your Android phone.
