Come hack on chestnuts!Permalink
What does your embedded project look like with 172 TFLOPs? 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.
