The Raspberry Pi 400 is a $70 keyboard that's also a computer

In the eight and a bit years since the first model launched, the Raspberry Pi has traditionally been sold as a modular computer. You buy the board separately, attach your own peripherals, insert an SD card and then get to work on your own computing project. The Foundation watched as third-parties — including Kano — built their own all-in-one PC solutions around the Raspberry Pi, leading it to create its own Desktop Kit, which bundled all of the necessary tech to deploy a fully-functional desktop or coding workstation. Now, it’s going one better with the launch of the Raspberry Pi 400 — a complete personal computer built inside a 78-key keyboard that starts at $70.

The Pi 400 has almost the exact dimensions of the official Raspberry Pi keyboard and hub, but with all of the extra ports and connectors needed to turn it into a PC. The power is provided by the same — albeit slightly tuned — quad-core Broadcom BCM2711 processor found in the Raspberry Pi 4, along with 4GB of RAM, dual-band WiFi, Bluetooth 5.1, Gigabit Ethernet and three USB ports (two USB 3.0 and one USB 2.0). There are also two micro HDMI ports, a GPIO header and a microSD card slot for OS and data storage.

The $70 Computer Unit is the no-frills option: you literally get the keyboard and will need add your own power and accessories. However, the $100 Pi 400 Computer Kit includes a localized power supply, mouse, a pre-formatted 16GB microSD card, a Beginner’s Guide and a 1M micro HDMI to HDMI-A cable. It’s very similar to the Desktop Kit but with even fewer parts.

The inspiration behind the Pi 400 came from “challenges for less-technical users in configuring a device with lots of parts, often without hands-on support because COVID-related restrictions on home visits,” confirmed Raspberry Pi CEO Eben Upton.

“The all-in-one form factor is about simplifying the setup for people who just want to use their Raspberry Pi as a PC. Fewer components on the desk means less clutter, faster setup and teardown times, and fewer opportunities to misconfigure the device. It actually also brings some cost savings, so the kit is significantly cheaper than the Pi 4 4GB Desktop Kit ($100 vs $120 RRP).”

The Raspberry Pi Desktop Kits will remain on sale for people who want the flexibility of the original form factor, or want to buy models with differing memory capabilities. The company doesn’t currently have any plans to offer a 2GB version of the Pi 400, due to the proportional cost saving being quite small, but may decide to offer a beefier model for “large corporate or educational deployments where the accumulated cost saving is worthwhile” further down the road.

For those of a certain age, the Pi 400 may look familiar; the '80s was full of all-in-one micro computers like the Commodore 64, ZX Spectrum, BBC Micro and Atari 800XL. "I was a BBC Micro and Amiga kid," said Upton, "without those platforms I, and lots of other people like me, would never have ended up in the engineering field." Continuing that push to help young people study computer science has always been a core part of the Raspberry Pi Foundation's mission, and Upton says "this is just the next phase of that journey."

The Raspberry Pi 400 is available to buy from today in the US, UK and France. The official list of resellers can be found here.
