Raspberry Pis are single-board computers that were originally developed with educational purposes in mind. Now, they’re widely used all over the world for a broad range of applications such as for home automation, home media centers, retro gaming, and more. The wide support from the Raspberry Pi community is part of what makes the Raspberry Pi so appealing as a first foray into physical computing.

Another draw is the wide range of accessories available, where no hardware or software experience is required to get started with physical computing. Many of these accessories are used at home, in the classroom, or in maker spaces. Thanks to the 40 GPIO pins (on most models), many of these accessories can be simply plugged in on top in one simple move. Smaller boards that add extra functionality are called HATs or pHATs.

Some of these accessories can even be made by yourself, with 3D printing and some tools, so to start off, why not create something practical? Even if you’re a newcomer to the Raspberry Pi ecosystem, there are plenty of 3D printable Raspberry Pi cases with files available online that won’t require any prior computing knowledge.

Without further ado, let’s check out some of the best and most popular Raspberry Pi accessories in 2021!

This is the official 7” Touchscreen display from the Raspberry Pi Foundation. This 800 x 480 display has 10-finger touch and on-screen keyboard functionality.

It’s large enough to create an all-in-one, integrated project such as an infotainment system or tablet, while still being small enough for portability. Connecting it to the Raspberry Pi is simple with an adapter board that handles both power and signal conversion.

There are two connections: the first is power through the Pi’s GPIO port, and the second is a ribbon cable to the DSI port on the Raspberry Pi. We recommend using the latest version of Raspberry Pi OS for this to work correctly. Head over to the Raspberry Pi’s software section to get it.

  • Features: 800 x 480 pixels, touchscreen
  • Connection type: Ribbon cable, GPIO
  • Price: $65-$100
