You can purchase a Raspberry Pi for as little as $5 (for the Raspberry Pi Zero) or more likely $35 (for the Raspberry Pi 4), but you'll need a few extra products to make it run. And, beyond that, there's a whole world of accessories that help you make the most of your Pi. 

Black Friday Raspberry Pi Deals

This Black Friday season is a great time to buy some accessories for your next Raspberry Pi project. Accessories and HATs provide limitless ways to expand your learning and fun. Breadboards, cameras and expansion boards can power time-lapse photography, robots and other fun projects. We're tracking all of the sales on our best Black Friday Raspberry Pi deals page.

As with any computer, on the Raspberry Pi, you’ll need a way to enter data and a way to see the interface, which usually means getting a keyboard, a mouse and a monitor. .However, you can opt for a headless Raspberry Pi install, which allows you to remote control the Pi from your PC. In that case, the minimum requirements are:

  • microSD card of at least 8GB, but the best Raspberry Pi microSD cards have 32GB or more. When you first set up a Raspberry Pi, you need to “burn” the OS onto it by using a PC, another Raspberry Pi or even a phone with microSD card reader.
  • Power supply: For the Raspberry Pi 4, you need a USB-C power source that provides at least 3 amps / 5 volts, but for other Raspberry Pis, you need a micro USB connection that offers at least 2.5 amps and the same 5 volts.

In addition, there are a number of accessory and add-on types that protect your Pi, add new features and make everything a lot more useful and fun. These include:

  • Cases: The best Raspberry Pi cases give you style, functionality and durability.
  • HATs (aka add-on boards): The best Raspberry Pi HATs let you do everything from adding motors to creating LED light shows.
  • Breakout Boards: To breakout the GPIO for easier access or to use via a breadboard. Essential for the new Raspberry Pi 400.
  • Camera Modules: The Raspberry Pi has its own special camera port and there's a whole ecosystem of compatible camera modules for it.
  • Cooling: Raspberry Pi 4 models in particular can get hot so fans and heatsinks help.
  • Electronic parts: You can make great projects and have a lot of fun with motors, sensors, transistors and other bits and bobs.

Overall, these are the best Raspberry Pi accessories. No matter what your needs or project, you’ll definitely need some of these.

3. Raspberry Pi Camera Module V2

Best Affordable Raspberry Pi Camera

Good image quality
Affordable price
No tripod mounting

If you need a Raspberry Pi camera, but don't want to spend more than $50 on the high quality module and then have to bring your own lens, the official Raspberry Pi Camera Module V2 is the one to get. This 8-MP camera uses a Sony IMX219 sensor that gives it really solid image quality, records video at up 1080p, 30 fps  and is a big improvement over the 5-MP OmniVision OV5647 that was in the V1 camera.

There are a number of third-party Raspberry Pi camera modules on the market, with some costing around $10 or less. However, most of these use the older, OV5647 sensor which provides far worse image quality.

Raspberry Pi 4 Official Power Supply

Best Raspberry Pi Power Supply

Provides just the right amount of power
Built for Pi
No on/off switch
Not the cheapest option

If you're going to use a Raspberry Pi 4, you need a USB-C power supply that offers at least 3 amps of juice with a roughly 5-volt output. We've found that the best USB-C laptop chargers are capable of delivering this kind of power (albeit often with 4.8 - 4.9 volts, which still works), but if you don't have a powerful charger handy or need one just for your Pi, the official Raspberry Pi power supply is your best choice.

Rated for 5.1 volts and 3 amps, the official Raspberry Pi 4 power supply has good build quality and a nice design. Available in black or white, it's a small rectangle, emblazoned with the Raspberry Pi logo and a strong, built-in Type-C cable that's 59 inches (1.5m) long. Unlike some third-party competitors, it doesn't come with an on / off switch, but it is compatible with cheap on / off adapters you can attach to the end. You may find competitors for a few dollars less, but the official Raspberry Pi 4 power supply is a sure thing.

If you are shopping for any other Raspberry Pi, including the Raspberry Pi Zero or Raspberry Pi 3 or below, you'll need a power supply that outputs to a micro-USB port and only requires 2.5 amps and 5 volts. There's also an official Raspberry Pi charger for these older models.

6. Pimoroni Explorer HAT Pro

Best Raspberry Pi HAT

Analog to digital conversion
Motor controller
LED lights
Built-in breadboard
No pass-thru for other HATs

The Raspberry Pi's 40 GPIO pins are arguably its most important feature. Using these pins (see our GPIO pinout), you can attach an entire universe of electronics, including motors, sensors and lights. There's a huge ecosystem of add-on boards, appropriately called HATs (hardware attached on top) that plug directly into the GPIO pins and matching the same layout as the Pi. These add on boards give you all kinds of added functionality, from LED light matrixes to touch screens and motor controllers for robotics projects. 

Sitting at the very top of our list of Best Raspberry Pi HATs, each of which has a different purpose, the Pimoroni Explorer HAT Pro provides a smorgasbord of features that you can use in a wide variety of projects. While the Raspberry Pi doesn't come with an analog to digital converter like Arduino does (see Raspberry Pi vs Arduino), the Explorer HAT Pro provides four ADCs you can use with joysticks or potentiometers. It also packs two motor controllers, four colorful LED lights, four touch pads and four crocodile clips for attaching other electronics. Oh and it comes with a small breadboard you can stick on top and use for mounting and wiring electronics. Every serious Raspberry Pi fan should have one of these on hand.

7. Pimoroni Fan Shim

Best Cooling for Raspberry Pi

Great cooling
HATs go on top of it
Expensive in the US

If you're using a Raspberry Pi 4, you definitely need some kind of cooling, whether it's a heat sink, an aluminum with passive cooling built in or, best of all, a fan. The Pimoroni Fan Shim is powerful, easy-to-install and unobtrusive. You just push it down onto the left most side of your GPIO pin header and it does a fantastic job of cooling your Pi. You can even use a Pimoroni Fan Shim on a Raspberry Pi 4 that's been overclocked all the way to 2.1 GHz, without seeing any throttling.

You can just let the Fan Shim run all the time or you can download Pimoroni's software, which allows you to set temperature thresholds for it.

8. Silicon Power 32GB 3D NAND microSD Card

Best Raspberry Pi microSD Card

Inexpensive
Leading performance
White surface you can write on
Slow boot times

Unless you've specifically configured yours to boot from an SSD (see our article on How to Boot Raspberry Pi from USB), every Raspberry Pi uses a microSD card as its primary storage drive. We maintain a list of the Best microSD cards for Raspberry Pi and have chosen the 32GB Silicon Power 3D NAND card as the top choice.

Unless you're hosting a media server or have a ridiculous amount of ROMS on a game emulator, a 32GB microSD card provides more than enough storage for Raspberry Pi OS and a ton of applications. The operating system and preloaded applications take up far less than 8GB by themselves.

In our tests, the Silicon Power 3D NAND microSD card had the fastest application open times and the best combination of random reads and writes. Considering that it's also less expensive than most 32GB cards and that its white surface provides a little room for you to write on it (with marker), this is currently the best card around.

9. GPIO Reference Board

Helpful Accessory

Helpful reference
Cheap
You can look this up online

Each of the Raspberry Pi's 40 GPIO pins has a different function so it's hard to keep track of which does what. For example, some of the pins provide I2C communication while others offer power and others are just for grounding. You can look at a GPIO pinout guide such as ours, but sometimes it's just easier to put the list of functions right on top of the pins.

GPIO reference boards are tiny, non-electronic headers that you place on top of the pins to show you which one has which name. There are many different brands and models for sale and all do pretty much the same thing so there's no need to be picky about which one you buy. Most have small holes on top that you can use to hang them on a keychain and take them wherever you go.

10. micro HDMI to HDMI Adapters

Must-Have for Pi 4

Very helpful and work well 
 You still need an HDMI cable 

While most of the earlier Raspberry Pi models have a single, full-size HDMI port, the Raspberry Pi 4 has dual micro HDMI ports that can each output to a monitor at up to 4K resolution. While there's a good chance you already have one or more HDMI cables lying around the house, most of us don't have micro HDMI cables, because it's a rarely used connector.

To connect the Raspberry Pi 4 to a screen, you'll either need a micro HDMI to HDMI cable or a micro HDMI to HDMI adapter you can connect an existing cable to. Cable Matters, a well-known and reputable brand, sells a pair of such adapters for just $10. That's much cheaper than a single micro HDMI to HDMI cable, which goes for $8 to 10 for just one. I've been using these Cable Matters adapters for more than a year now and they've worked really well.

Freenove LCD 1602 Starter Kit

11. Electronics Kit with Breadboard, Wires

Great for learning
Helpful for prototyping
No soldering necessary

You can use your Raspberry Pi as a game emulator, a server or a desktop PC, but the real fun begins when you start connecting electronics to its GPIO pins. Of course, to even get started playing with GPIO connectors, you need some interesting things to connect to them such as lights, sensors and resistors.

The market is filled with electronics kits that come with a slew of LED lights, resistors, jumper cables, buttons and other bits and bobs you need to get started. Most importantly, all of these kits come with at least one breadboard, a white plastic surface filled with holes you can use to route and test circuits, no soldering required. 

There are plenty of good kits from no-name brands on Amazon, but the Freenove LCD 1602 Starter kit caught our eye, because it comes with an ADC chip for analog-to-digital conversion, an LCD text screen and a GPIO extension board you can use to route all your pins over to the breadboard at once.

USB 3 microSD Card Reader

12. USB 3 microSD Card Reader

Need it to read and write
PC with USB port quired 

In order to write Raspberry Pi OS (or a different OS) to a microSD card, you'll need some kind of microSD card reader that you can attach to your PC. Just about any make or model will do as long as it reads SDHC and SDXC cards and, preferably, connects via USB 3.0. I've been using the Jahovans X USB 3.0 card reader, which currently goes for $5.99, for almost a year now and it has worked really well.

You can also attach a microSD card reader to your Pi and use it to create a disk image backup of your Raspberry Pi

Raspberry Pi Zero Official Case

13. Raspberry Pi Zero Official Case

Best Case for Raspberry Pi Zero

GPIO Access
Camera Access
Official Pi design
Can't have both GPIO and Camera at once

We're not huge fans of the Official Raspberry Pi 4 case, because it covers the GPIO pins and camera slots. However, the Official Raspberry Pi Zero case is a completely different as it comes with three different covers: one which has a camera hole (so you can make a Raspberry Pi body camera), another which exposes the GPIO pins and a third which covers the whole thing.  The official Raspberry Pi Zero case also has the official burgundy and white colors of the Raspberry Pi Foundation.

    Just got Argon One. It's really beautifull case but can't cool RPI4B @2ghz for 20mins on full load. Cheapest Chinese case with heatsinks and fan all for 4USD have much better performance.

    Strange. See https://magpi.raspberrypi.org/articles/group-test-best-raspberry-pi-4-thermal-cases-tested-and-rankedIt should have enough power to cool it, albeit with the help of a fan. Does it have proper thermal contact?
    If you need more performance... well.. look at the only other case that beat it in that review.

    There's some other comparison over here:
    https://github.com/nschloe/stressberrybut be warned, it doesn't record ambient temperatures, which adds an offset. Hard to compare exactly.

    And if you are after some extreme cooling, see this
    RbzKM5XxlOAView: https://youtu.be/RbzKM5XxlOA
    Have fun ;)

    Just FYI, I have my RPI4 4GB (or a second one with 8GB) OC'ed to 2100MHz, over_voltage=6, core at 550MHz. Typical temperature deltas:
    Idle - 10°C
    Firefox running - 14°C
    Max load (stress-ng or linpack) - 22°C
    All passive, not with that 60mm Noctua fan. It slashes it even more.
