The Raspberry Pi Foundation has released the Raspberry Pi 400, its first all-in-one PC, built into a keyboard.
On the face of it, the Raspberry Pi 400 looks like just another Bluetooth keyboard. Flip it around though and you’ll notice the ports that you’ll usually find on the sides of your laptop or on the back of a desktop PC.
The keyboard sports a pair of micro HDMI ports that can each output 4K video, two USB 3.0 ports, a single USB 2.0 port, and even an Ethernet port. There’s also a USB-C port for powering the device and it also features a microSD card slot for storage. As usual, no Raspberry Pi device is complete with GPIO header for attaching add-on devices known as Hardware-on-Top or HAT.
