The Raspberry Pi 400 is a Raspberry Pi 4 built into a keyboard. Because it is basically a Raspberry Pi 4, the Raspberry Pi 400 has almost the same specifications as the Raspberry Pi 4 with 4 GB of memory. As such it also has Wi-Fi and Bluetooth. There are some differences, however.

To fit the Raspberry Pi 4 inside a keyboard while keeping its connectors accessible, the board has been redesigned. Most of the Raspberry Pi 4’s connectors, including the 40-pin extension connector, are available at the rear side of the device, but not all.

Soft power On/Off button

Compared to the Raspberry Pi 4, the Raspberry Pi 400 is more accessible to newbies, simply because it is nicely packaged. It also has a soft power On/Off button, which is good. 

Missing : camera, display & A/V connectors

The Raspberry Pi 400 did not inherit the camera, display, and analogue A/V connectors. Dropping the display and A/V connectors seems logical as sound and video are transported perfectly fine over HDMI (of which there are two); the camera can simply be replaced by a USB webcam.

The microSD card connector finally has become a push-push type, which makes replacing the SD card much easier than on other Raspberry Pis, especially when these were mounted inside a case. For cost, size or other reasons, the Ethernet connector does not have LEDs anymore.
