Raspberry Pi 400

Released November 2020

A Raspberry Pi 4 built into a compact keyboard, with a 1.8GHz quad-core Arm Cortex-A72 and 4 GB of memory, as a complete low-cost desktop computer that plugs into a monitor or TV.

What reviewers say

Reviewers agree it is a neat, affordable computer-in-a-keyboard that makes getting started easy, with cooling good enough for a higher default clock than the Pi 4 and room to overclock. The common criticisms are awkward access to the GPIO header for add-on boards and no camera or display connectors; Wired found the keyboard comfortable for long typing sessions.
