Best Raspberry Pi Accessories of 2021


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. 

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.
