Older hardware

Still on sale and still enough for Home Assistant or Pi-hole, but a Pi 5 or an N150 box is better value now.

What it is good for

Derived from the specs

Our rules applied to its specs. The reasons come from the data in the specification table. How the verdicts are decided

  • Home AssistantGood
    • Official or well-supported Home Assistant OS image
    • microSD or USB storage only: use a USB SSD for reliability
    • Low power for 24/7 use
  • Media serverLimited
    • Hardware encoder for H.264 only
    • Decodes HEVC 10-bit in hardware, not AV1
  • Homelab / ProxmoxLimited
    • Arm processor: Docker works, Proxmox VE does not
    • Up to 8 GB of RAM for containers
  • Router / firewallLimited
    • One network port: only as a 'router on a stick' with VLANs and a managed switch
  • NASLimited
    • No internal drive slot: USB drives only
  • DesktopLimited
    • Linux desktop on Arm: fine for browsing, coding and learning, slow with heavy sites
  • Electronics / GPIOGreat fit
    • 40-pin GPIO header
    • The most tutorials, HATs and libraries of any board

Configurations and where to buy

Prices are editorial references (launch price and a typical street price on the date shown), not live prices. In 2026 the memory shortage has pushed many prices well above launch.

Prices are shown only if updated in the last 24 hours and may change; the retailer’s price at checkout applies. We may earn a commission from these links at no cost to you. Affiliate disclosure

Overview

Editorial opinion

Best for: Replacing an old Pi, or projects that need the Pi 4's lower power draw.

Editorial opinionWould we buy it today?

Only if you need exactly a Pi 4. Otherwise get a Pi 5 or a mini PC.

Pros and cons

Editorial opinion

Pros

  • Mature software and huge community
  • Low power (about 3–4 W idle)
  • Fits every Pi 4 case and HAT

Cons

  • Much slower than a Pi 5
  • No PCIe: SSDs only over USB
  • Prices up in 2026
