Raspberry Pi 400 vs Raspberry Pi 4: The Differences
The Raspberry Pi 400 is an all new form factor from Raspberry Pi. It features all the power of a Raspberry Pi 4 model B built into a keyboard. On the back, 3 full size USB ports allow you to connect mice, cameras, and other peripherals. A 2x40 header breaks out all the pins present on a standard Raspberry Pi 4 model B, allowing you to access GPOI and power pins for HATs or other electronics. Two Micro HDMI ports allow you to connect dual 4k monitors.
