Mounting & usage guide

Mounting

Footprint 85 × 56 mm, 17 mm tall (about 0.08 litres).
No VESA mount: place it on a shelf or a rack tray, or use a universal strap-style mini PC holder.

Cooling & heat

Low-power ARM SoC: a passive heatsink or small fan keeps it cool even running 24/7.
Clean dust from the vents every 6-12 months to keep temperatures and power draw low.

Recommended use cases

Always-on Home Assistant: at about 3 W idle it is cheap to run 24/7.
OpenWrt, Pi-hole, Home Assistant OS or small ultra-low-power home servers.
