Raspberry Pi 400 is a compact personal computer built into a keyboard, combining an ARM-based computer with a full keyboard for easy desktop use.
Key Points
• All-in-one keyboard PC — the computer hardware is integrated into a compact keyboard body.
• Processor: Broadcom BCM2711 64-bit quad-core ARM Cortex-A72 @ 1.8 GHz.
• Memory: 4 GB LPDDR4 RAM.
• Ports & Connectivity:
o 2 × USB 3.0, 1 × USB 2.0
o Dual micro-HDMI (up to 4Kp60)
o Gigabit Ethernet
o Wi-Fi and Bluetooth 5.0
o 40-pin GPIO header for projects.
• Storage: micro SD card slot for OS and files.
• OS: Runs Raspberry Pi OS (Linux), plus many other options.
What it’s used for
• Learning coding and computing
• Basic productivity (web, documents, media)
• Home labs and lightweight development
• DIY electronics via GPIO
It’s small, affordable, and ideal for education or hobbyist projects, but not designed for heavy workloads like high-end gaming or large-scale video editing.
