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 AssistantGreat fit
- Official or well-supported Home Assistant OS image
- Takes an SSD or eMMC for the system
- Low power for 24/7 use
Media serverGreat fit
- Intel Quick Sync: the best-supported transcoding in Plex and Jellyfin
- Decodes HEVC 10-bit and AV1 in hardware
Homelab / ProxmoxGood
- 16 GB of RAM, soldered: it cannot grow
- 4 threads
Router / firewallLimited
- One network port: only as a 'router on a stick' with VLANs and a managed switch
NASLimited
- 1 internal drive slots (1× M.2)
- 2.5 GbE network
- A single drive: no mirror, so keep a backup elsewhere
DesktopGood
- Windows 11 supported
- 4 threads, up to 16 GB of RAM
- 2 displays at once
- Fine for office and web; slow with many tabs or photo editing
Electronics / GPIOGood
- GPIO header
- Raspberry Pi HATs and libraries do not always work unchanged

Overview

Editorial opinion

Best for: x86 software (Windows, Home Assistant OS, Docker images) on a Pi-sized board with GPIO.

Editorial opinionWould we buy it today?

Yes if you want x86 in a Pi-sized board; for a plain server a boxed N150 is easier.

Pros and cons

Editorial opinion

Pros

x86: runs any PC operating system
Intel 2.5 GbE and NVMe
40-pin header through an RP2040

Cons

RAM soldered
Runs hot without a good heatsink
GPIO goes through a microcontroller, not the CPU
