Buying a Raspberry Pi is only the beginning. To get the best experience, you also need the right accessories.

A Raspberry Pi on its own is just the core board. To power it properly, protect it, cool it, store files, and actually build useful projects, you need a few supporting items around it. Raspberry Pi’s official accessories lineup includes power supplies, cases, SD cards, SSDs, keyboards, cameras, displays, and expansion boards, which reflects how important the accessory ecosystem is to the overall experience.

In this guide, we’ll cover the essential accessories every Raspberry Pi user should consider, from absolute must-haves to optional upgrades that make your setup faster, cleaner, and more enjoyable.

Why Accessories Matter for Raspberry Pi

Unlike a typical desktop computer, a Raspberry Pi often ships as a bare board. That means the user is responsible for choosing the parts that make it practical to use day to day.

The right accessories improve reliability, performance, thermals, storage speed, and ease of use. This matters even more with Raspberry Pi 5, where Raspberry Pi explicitly recommends a higher-power 27W USB-C power supply and official fan-based cooling options.

1. A Proper Power Supply

If there is one accessory you should never treat as optional, it is the power supply.

Using a weak or poor-quality power adapter can cause instability, random reboots, USB issues, or poor performance. Raspberry Pi specifically recommends a high-quality 5V 5A USB-C power supply for Raspberry Pi 5, such as the official 27W USB-C Power Supply. For Raspberry Pi 4, Raspberry Pi recommends its 3A USB-C supply.

For most users, this means:

• use the correct official supply when possible

• avoid cheap no-name chargers

• match the adapter to your Pi model

A reliable power supply is not exciting, but it prevents a huge number of beginner problems.

2. A microSD Card

A microSD card is one of the most essential Raspberry Pi accessories because it is the most common boot and storage medium for Raspberry Pi systems. Raspberry Pi even sells official SD cards as part of its accessory range.

Without a good microSD card, your Raspberry Pi cannot easily run Raspberry Pi OS in the standard beginner setup. A low-quality card can make the system feel slow and can be more prone to corruption over time.

What matters most here is reliability. For beginners, a good-quality microSD card is one of the simplest ways to avoid headaches.

3. A Protective Case

A case protects the board from dust, accidental contact, and physical damage. It also makes your Raspberry Pi setup look cleaner and more finished.

Raspberry Pi’s official case for Raspberry Pi 5 is a four-part enclosure with an integrated active cooling fan designed to keep the board at a comfortable operating temperature under heavy load.

That tells you something important: a case is no longer just cosmetic. On modern Raspberry Pi setups, especially Pi 5, the right case can also be part of your cooling strategy.

A good case is especially useful if your Pi will sit on a desk, stay connected all day, or be used in a permanent project.

4. Cooling Solution: Fan or Active Cooler

Cooling has become much more important with Raspberry Pi 5.

Raspberry Pi’s hardware documentation says Pi 5 users should use one of the official fan options: the Active Cooler or the official Raspberry Pi 5 case with integrated fan. Raspberry Pi also notes that the Active Cooler case is the better performer for overclockers.

For lighter Raspberry Pi 4 projects, passive cooling or even no special cooling may be enough in many cases. But for Raspberry Pi 5, especially under heavier workloads, a proper cooling accessory is a smart buy because it helps sustain performance and prevents thermal throttling. That conclusion follows from Raspberry Pi’s explicit cooling guidance for the board.

If you plan to browse, code, emulate, compile software, or run demanding services, cooling is not optional in practice.

5. HDMI Cable and Display Setup

To use Raspberry Pi like a desktop, you need a monitor or TV and a compatible HDMI cable setup.

Most Raspberry Pi users will want this at least during initial setup, troubleshooting, or learning. Even if you later run your Pi headless, a display connection is often useful when getting started.

This is one of those accessories people forget to include when they first buy the board.

6. Keyboard and Mouse

If you are using Raspberry Pi as a desktop computer, you need a keyboard and mouse. Raspberry Pi includes official keyboard and mouse products in its accessory catalog.

These are not technically required for every project, especially on headless server setups, but they are essential for beginners because they make setup, exploration, and everyday use much easier.

For anyone just entering the Raspberry Pi world, having a proper keyboard and mouse turns the board into a more approachable computer rather than a bare electronics platform.

7. SSD or Fast External Storage

This is where your Raspberry Pi setup can go from decent to excellent.

Raspberry Pi offers official SSDs in 256GB, 512GB, and 1TB sizes, and states that SSD quality is a critical factor in the overall user experience.

For Raspberry Pi 5 users, this matters even more because the board supports PCIe-based expansion through accessories like the M.2 HAT+, which Raspberry Pi says can connect NVMe drives and other PCIe peripherals at up to 500MB/s.

Raspberry Pi also sells an SSD Kit that bundles the M.2 HAT+ with a Raspberry Pi SSD, and notes that the kit is designed to work alongside the Raspberry Pi 5 Active Cooler.

For users running a desktop setup, server, large media library, or development environment, fast SSD storage is one of the best upgrades available.

8. M.2 HAT+ for Raspberry Pi 5

If you use Raspberry Pi 5 and want faster storage or advanced expansion, the M.2 HAT+ is one of the most useful accessories you can buy.

Raspberry Pi says the M.2 HAT+ connects M.2 peripherals such as NVMe drives and AI accelerators to Raspberry Pi 5’s PCIe 2.0 interface, supporting up to 500MB/s transfer speeds. Raspberry Pi also offers a Compact version designed to fit inside the Raspberry Pi 5 case while allowing space for the integrated fan.

This is not a mandatory purchase for every beginner, but it becomes highly valuable if you want:

• faster boot and load times

• more responsive storage

• AI accessory support

• a more advanced Pi 5 setup

For power users, this accessory can be transformative.

9. Camera Module

A camera is one of the best accessories for users who want to go beyond desktop use and start building projects.

Raspberry Pi includes official camera boards and an AI Camera in its accessories lineup.

A camera lets you build:

• security projects

• timelapse systems

• object detection projects

• smart doorbells

• computer vision experiments

The AI Camera and AI HAT range also show that Raspberry Pi is pushing more strongly into on-device vision and edge AI use cases. Raspberry Pi says its AI HATs for Pi 5 contain Hailo NPUs for local hardware-accelerated AI inference.

For many users, a camera is not essential on day one, but it is one of the most exciting accessories to grow into.

10. Official Touch Display or External Screen

If you want a more dedicated Raspberry Pi build, a display accessory can make a huge difference.

Raspberry Pi’s accessories documentation includes Touch Display 2 and monitor products, showing that display-based projects remain an important part of the ecosystem.

A touchscreen is especially useful for:

• dashboards

• smart home panels

• wall-mounted interfaces

• kiosk projects

• custom control stations

This becomes a strong add-on once you move from experimenting to building something permanent.

11. USB Accessories and Hubs

As your setup grows, USB expansion becomes more important.

Raspberry Pi’s accessory lineup includes official USB accessories such as a USB 3 Hub and flash drives.

This matters if you want to connect:

• external storage

• keyboard and mouse

• game controllers

• adapters

• audio peripherals

• development tools

A USB hub is especially useful when one Raspberry Pi starts becoming the center of several connected devices.

12. GPIO-Friendly Add-ons for Projects

One of Raspberry Pi’s biggest strengths is that it is not just a mini computer; it is also a project platform.

Raspberry Pi’s accessories portfolio includes boards like Build HAT, Sense HAT, and AI add-ons, which shows how central expansion and hardware interfacing are to the platform.

For users interested in electronics, automation, or education, useful add-ons can include:

• breadboards

• jumper wires

• sensors

• LED kits

• HATs

• relays

• robotics boards

These are not universal must-haves, but for maker-style projects, they quickly become essential.

The Core Accessory Kit Most Users Should Start With

If you want the practical shortlist, most Raspberry Pi users should start with these essentials:

• the correct power supply

• a good microSD card

• a case

• a cooling solution, especially for Raspberry Pi 5

• HDMI cable

• keyboard and mouse

• optional SSD upgrade for better performance

That combination covers the vast majority of beginner and everyday needs, and it aligns closely with Raspberry Pi’s current official accessory ecosystem around power, cases, storage, and peripherals.

Which Accessories Are Most Important for Raspberry Pi 5?

For Raspberry Pi 5 specifically, the most important accessories are:

• the official 27W USB-C power supply

• proper active cooling

• a compatible case

• optional M.2 HAT+ and SSD for a faster setup

That is because Raspberry Pi 5 has higher power expectations, official fan-based cooling support, and built-in PCIe expansion potential that earlier mainstream Raspberry Pi boards did not emphasize in the same way.

Final Thoughts

The best Raspberry Pi experience does not come from the board alone. It comes from pairing the board with the right accessories.

At a minimum, every Raspberry Pi user should think seriously about power, storage, protection, and cooling. From there, accessories like SSDs, cameras, displays, and HATs can take your setup from basic to impressive.

The good news is that you do not need everything at once. Start with the essentials, then expand based on what you want to build.

That is one of the best things about Raspberry Pi: your setup can grow with your skills.
