What is the Raspberry Pi 400?

A look inside Raspberry Pi 400

Raspberry Pi 400 is a new-age Commodore 64; a powerful personal computer kit packed into a compact, portable keyboard that integrates the core components of a Raspberry Pi 4 single board computer, including the powerful processor, memory, and input/output ports. 

Featuring a quad-core 64-bit processor and wireless networking, Raspberry Pi 400 is capable of a number of uses including surfing the web, multimedia playback, word processing, programming and running apps through the Raspberry Pi OS environment. RPi 400 comes with 4GB of RAM (although an anonymous user has remarkably managed to tinker their way around that to create the first-ever 8GB Raspberry Pi 400).

This unconventional Raspberry Pi model supports dual display output and 4K video playback and can be connected to any display through two micro HDMI cable connections. It also features a built-in microSD card slot for storage as well as 3 USB ports and a 40 pin GPIO header that allows users to expand hardware and connect peripherals. Lastly, it’s offered in a variety of different keyboard layouts for 12 languages. 

Overall, the Raspberry Pi 400 is an affordable and user-friendly computer-in-a-keyboard, ideal for those interested in learning about programming or setting up a portable workstation for a wide range of applications.

Differences between Raspberry Pi 400 and Raspberry Pi 4

Let’s start with the obvious: Raspberry Pi 4 comes as a standalone board while Raspberry Pi 400 is basically a Raspberry Pi 4 integrated into a compact keyboard. But apart from the form factor, there are a few more minor differences between the two. 

  • Raspberry Pi 4 features an additional USB 2.0 port 
  • Raspberry Pi 400 only comes with 4GB of RAM. On the contrary, with Raspberry Pi 4 Model B you can choose between 1, 2, 4 or 8 GB of RAM
  • Raspberry Pi 4 can support Power over Ethernet (PoE) with a separate PoE HAT
  • Raspberry Pi 4 features the standard GPIO header that’s backward compatible with previous boards whereas Raspberry Pi 400 features a horizontal GPIO header at the rear end of the keyboard
  • Raspberry Pi 400 lacks the 3.5mm audio port of the Raspberry Pi 4
  • Raspberry Pi 400 features a built-in heat sink that helps with heat dissipation

Raspberry Pi 400 Uses

The technical specs, affordability and compact design of Raspberry Pi 400 make it a prevalent choice for a wide variety of uses. To begin with, it can be used as a portable desktop computer for online browsing and daily tasks, a complete entertainment system or a gaming console. In addition, its advanced connectivity options make it an ideal Raspberry Pi device for any kind of DIY project, home automation and IoT device management. It is also widely used as a creative STEM educational tool. Usually paired with a Raspberry Pi screen, the RPi 400 is used as a portable computer in a keyboard that allows students to try their hand at programming, experiment with robotics and set up their own projects.

Finally, the Raspberry Pi 400 is an affordable, easy-to-use and undeniably cool machine for digital signage. 

Raspberry Pi 400 for Digital Signage

Raspberry Pi 400 is an exceptionally efficient solution for deploying a digital signage system for numerous reasons. First off, it supports 4K video playback and dual display output functionality which means you can easily connect it directly to any two screens or displays over HDMI. 

Furthermore, its self-contained single board computer form simplifies the setup process or the integration with existing digital signage displays while minimizing hardware footprint. In addition, the 40 pin GPIO header can be used for interfacing peripherals, sensors, screens and hardware to enhance the functionality of your digital signage system.  

Finally, despite the impressive processing power and all its features, the Raspberry Pi 400 is a very cost-effective solution compared to other dedicated digital signage media players. 

The only thing you’ll need to get started is a user-friendly digital signage content management software. Luckily for you, you can easily turn your Raspberry Pi 400 into a Yodeck player. Yodeck’s digital signage CMS will allow you to create, edit, schedule and manage content remotely through a central platform.
