Raspberry Pi 400 overview
The Raspberry Pi 400 is a complete personal computer built into a compact keyboard form factor. Featuring a quad-core 64-bit processor, 4GB of RAM, wireless networking, dual-display output, and 4K video playback, as well as a 40-pin GPIO header, it's the most powerful and easy-to-use Raspberry Pi computer yet.
The Raspberry Pi 400 brings back the old "CPU under the Keyboard" aesthetic and works remarkably well. The compact keyboard measures just over 11 x 4.6 x 0.7 inches (283 x 120 x 20 mm) and it is fairly comfortable to type on.
