Pi-hole is a DNS blocker that protects your devices from unwanted ads, analytics, malware, and other content. When your devices try resolving a new domain name (e.g., analytics.google.com), Pi-hole blocks the undesirable domain while allowing others to be resolved successfully.

Pi-hole was made to run on low-end hardware. There are many options out there, but I'll help you find the best one for your needs. First off, let's go over the system requirements for running Pi-hole.

Should You Use Ethernet or Wi-Fi With Pi-hole?

Pi-hole will work when your Raspberry Pi is connected to either Wi-Fi or Ethernet. Ethernet may provide a slightly faster response time and a more stable connection than Wi-Fi. However, you most likely won't notice much of a difference between the two.

MicroSD Card Capacity

While a 4 GB microSD card works fine, a 32 GB microSD card is recommended since there's not much price difference. A larger microSD card would allow you to repurpose the Raspberry Pi in the future or use it for multiple tasks.

I recommend the SAMSUNG 32GB microSDHC Card on Amazon (affiliate link) if you don't already have one and aren't getting one in a kit.

Best Raspberry Pi Devices for Pi-hole

Choosing the best Raspberry Pi for Pi-hole depends on what appeals to you most and how much flexibility you want for other projects. Read through the descriptions of each to see what best fits your needs.

Raspberry Pi 400 All-in-One

The Raspberry Pi 400 is the best out of the three. It has a slightly faster processor than the Raspberry Pi 4 Model B. It also runs marginally cooler due to the narrow board design. This one is the easiest to get up and running, as it has Raspberry Pi OS pre-loaded and is fully assembled. The Raspberry Pi board is built into the keyboard, which makes it very portable.

  • 1.8 GHz quad-core 64-bit processor
  • 4 GB RAM
  • The "case" is also the keyboard
  • It comes with a mouse, 16 GB microSD card pre-loaded with Raspberry Pi OS, power supply, 3 ft micro HDMI to HDMI A Cable, and a beginner's guide
  • Supports dual-band (2.4GHz and 5.0GHz) Wi-Fi
  • Bluetooth 5.0
  • Gigabit Ethernet port
  • Two USB 3.0 ports and a USB 2.0 port
  • Two micro-HDMI ports (supports 4k resolution)
  • 40-pin GPIO port

Raspberry Pi 4 (Model B) Starter Pro Kit

The Raspberry Pi 4 Model B is great if you don't want the keyboard of the Raspberry Pi 400 but want something faster with more flexibility than the Raspberry Pi Zero W. This Raspberry Pi requires some assembly, so if you want the experience of putting it together, it's a good choice. Plus, it's easier to customize if you're going to modify it later.

  • 1.5 GHz quad-core 64-bit processor
  • 4 GB RAM
  • It comes with a black case, fan, power switch, heat sinks, 6 ft micro HDMI cable, power supply, a 32GB microSD card, and a microSD card reader
  • Supports dual-band (2.4GHz and 5.0GHz) Wi-Fi
  • Bluetooth 5.0
  • Gigabit Ethernet port
  • Two USB 3.0 ports and two USB 2.0 ports
  • Two micro-HDMI ports (supports 4k resolution)
  • Included microSD card comes with "New Out Of Box Software" (NOOBS) for installing Raspberry Pi OS.
  • 40-pin GPIO port
  • Raspberry Pi 4 Starter Pro Kit on Amazon (affiliate link). Raspberry Pi 4 Starter PRO Kit

Raspberry Pi Zero W (Wireless) Starter Kit

The Raspberry Pi Zero W is the lowest-cost and smallest kit option. It has a slower processor along with less RAM than the other two. This Raspberry Pi will still work for Pi-hole, though. It just may not have as much flexibility included when compared with the others.

  • 1 GHz single-core processor
  • 512MB RAM
  • It comes with a white/red case (3 interchangeable lids), 16 GB microSD card, USB OTG adapter, mini HDMI adapter, heat sink, and power supply
  • Supports dual-band (2.4GHz and 5.0GHz) Wi-Fi
  • Bluetooth 4.1
  • No Ethernet port
  • One micro-HDMI port (720p resolution or below recommended)
  • One micro USB port
  • Included microSD card comes with "New Out Of Box Software" (NOOBS) for installing Raspberry Pi OS.
  • 40-pin GPIO port
