What Accessories Do I Need for a Raspberry Pi? 9 Must-Haves for 2026 🎉

So, you’ve got your shiny new Raspberry Pi out of the box, but now you’re staring at it, wondering: “What accessories do I actually need to get this little marvel up and running—and maybe even supercharged?” You’re not alone. At Why Pi™, we’ve seen countless beginners and pros alike get tangled in the jungle of power supplies, cases, HATs, and cables. Spoiler alert: not all accessories are created equal, and picking the right ones can save you from endless frustration (and those infamous rainbow squares of doom).

In this ultimate guide, we’ll walk you through 9 essential accessories that every Raspberry Pi user should consider in 2026, whether you’re building a media center, a home automation hub, or an industrial IoT beast. Plus, we’ll share insider tips from our own lab experiments—like how a £2 heatsink saved us from a meltdown or why the official power supply is worth every penny. Ready to unlock your Pi’s full potential? Let’s dive in!

Key Takeaways

  • Power supply quality is king: The official Raspberry Pi USB-C PSU ensures stable voltage and prevents unexpected shutdowns.
  • Storage speed matters: Use A1/A2-rated microSD cards like SanDisk Extreme Pro for fast, reliable performance.
  • Cooling is crucial: Passive or active cooling solutions prevent thermal throttling and extend your Pi’s lifespan.
  • Choose accessories based on your project: From touchscreen displays to industrial-grade HATs, pick what fits your use case.
  • Engage with the community and official docs for troubleshooting and inspiration.

⚡️ Quick Tips and Facts About Raspberry Pi Accessories

  • Every Pi needs juice: A 5.1 V, 3 A USB-C supply is non-negotiable for a Pi 4; anything less and you’ll be chasing rainbow-square ghosts.
  • Class-A1 (or faster) microSD = fewer “why is my desktop frozen?” moments.
  • Heat kills performance—even a ÂŁ2 aluminium heatsink can throttle temps by 15 °C.
  • GPIO is 3.3 V logic; shove 5 V in and you’ll let the magic smoke out.
  • Most “Pi starter kits” on Amazon bundle a generic Chinese PSU—swap it for the official Raspberry Pi Foundation one and halve your crash logs.

Curious how we learnt this? We once ran a head-less Pi Bitcoin node on a phone charger. The blockchain never synced, but the wallpaper of undervolt warnings was… memorable. 😅

🔍 Understanding Raspberry Pi: A Brief Overview and Evolution

Video: Top 5 Raspberry Pi DIY Projects of All Time.

Back in 2012 the OG Pi arrived with a scrawny 700 MHz single-core CPU and 256 MB RAM. Fast-forward to 2024: the Pi 5 bursts past 2 GHz, ships with PCIe, and can transcode 4K HDR. With each generation the “must-have” accessory list mutated—composite cables gave way to micro-HDMI, micro-USB bowed to USB-C, and those tiny 26-pin headers ballooned to 40 pins of GPIO goodness.

If you’re brand-new, skim our gentle intro at https://www.whypi.org/raspberry-pi/ then pop back—this guide assumes you’ve unboxed a board and are now staring at it like, “What sorcery do I need next?”

❓ Frequently Asked Questions About Raspberry Pi Accessories

Video: I Control EVERYTHING with this Raspberry Pi.

How do I choose the right display for my Raspberry Pi setup?

Choosing a display depends on your project goals and environment. For portable or touch-interactive projects, the Official 7-inch Raspberry Pi Touchscreen offers great resolution and multi-touch support. If you want ultra-low power or retro aesthetics, consider OLED or small TFT displays like those from Waveshare. For media centers or desktop use, any HDMI-compatible monitor or TV works fine—just ensure you have the correct micro-HDMI to HDMI cable or adapter.

Additional considerations:

  • Resolution and refresh rate for smooth video playback.
  • Touch capability if you want to avoid external input devices.
  • Power consumption, especially for battery-powered projects.

What peripherals should I get for a Raspberry Pi media center?

For a smooth media center experience, you’ll want:

  • A reliable power supply (official PSU recommended).
  • A fast microSD card or external SSD for media storage.
  • A wireless keyboard with integrated touchpad like the Logitech K400 Plus for easy navigation.
  • A good HDMI cable to connect to your TV or monitor.
  • Optional: a USB DAC or sound card for improved audio quality.

Are cooling accessories necessary for Raspberry Pi performance?

Yes, especially for Pi 4 and Pi 5 models running intensive tasks. The CPU can reach temperatures above 80 °C under load, triggering thermal throttling that slows performance. Passive cooling cases like the FLIRC or active cooling solutions like the ICE-Tower fan can keep temps in check, ensuring your Pi runs at full speed without overheating.

What cables are essential for connecting a Raspberry Pi?

  • Power cable: USB-C for Pi 4/5, micro-USB for older models.
  • HDMI cable: Micro-HDMI to HDMI for Pi 4/5; standard HDMI for older models.
  • Ethernet cable: Optional, for wired network connections.
  • USB cables: For peripherals or USB hubs.

Always choose high-quality cables to avoid voltage drops and signal interference.

Which microSD card is best for Raspberry Pi projects?

We recommend SanDisk Extreme Pro or Kingston Canvas Go! Plus cards with at least A1 or A2 speed class. These cards offer fast random read/write speeds critical for OS responsiveness and longevity. Avoid cheap no-name brands to reduce corruption and failures.

Do I need a case to protect my Raspberry Pi?

While not strictly necessary, a case is highly recommended. It protects against dust, accidental shorts, and physical damage. Cases like the FLIRC also provide passive cooling. If you prefer open-air setups for better airflow, consider using standoffs to keep the board elevated and safe.

The Official Raspberry Pi USB-C Power Supply is the safest bet, delivering stable 5.1 V at 3 A for Pi 4 and 5. Using generic or underpowered supplies can cause undervoltage warnings and instability. For portable or industrial setups, consider PoE+ HATs or UPS solutions like PiJuice Zero.

What type of HDMI cable works with Raspberry Pi?

For Pi 4 and 5, use micro-HDMI to HDMI cables rated for HDMI 2.0 or higher to support 4K video at 60 Hz. For older Pis with full-size HDMI, standard HDMI cables suffice. Avoid cheap cables that cause flickering or no signal.

Are USB peripherals necessary for Raspberry Pi setup?

Not always. If you run your Pi headless (no monitor), you can SSH or VNC in remotely. However, for initial setup or media center use, a keyboard and mouse (or combo devices like Logitech K400 Plus) make life easier.

How can I connect a Raspberry Pi to a monitor or TV?

Use a micro-HDMI to HDMI cable (Pi 4/5) or a standard HDMI cable (older models). Connect the HDMI end to your display and the micro-HDMI to the Pi. For older TVs without HDMI, adapters like HDMI-to-VGA or HDMI-to-DVI can work but may require additional power.

What cooling options are available for Raspberry Pi?

  • Passive cooling: Heatsinks, aluminum cases (e.g., FLIRC).
  • Active cooling: Small fans (e.g., ICE-Tower), fan HATs.
  • Hybrid: Cases with built-in fans and heatsinks.

Choose based on your workload and noise tolerance.
