Hands-on with the Turing Pi 2!
The Turing Pi 2 is quite an exciting project that might even be a game-changer when it comes to homelab. With it, you can set up Raspberry Pi Compute Modules as individual servers, and even cluster them! The Turing Pi 2 gives you access to many additional features that Compute Modules wouldn’t normally have access to, such as mPCIe, SATA, and more. This gives you access to build a data-center in a box, and Jay gives it a first-look on the channel in this video.
