Housed inside a keyboard, the Raspberry Pi 400 is the first Raspberry Pi that doesn’t come as a bare computer board, but as a nicely finished consumer product instead. The Raspberry Pi 400 is based on the Raspberry Pi 4, so it is not completely new, but its shape is. The Pi 4 was reshaped to fit inside the keyboard, and its connectors were moved to make them available on the rear of the device, bringing back memories of famous computers from the eighties like the Commodore 64, VIC-20, ZX-81, ZX Spectrum, etc.
