Technical specifications

Idle [source]3 W

Under load [source]7 W

Estimated 24/7 average3.8 W

Yearly cost (€0.25/kWh)8.32 €

Average based on 80% of the time at idle and 20% under load, running 24/7: 33 kWh/year. Adjust the inputs to match your usage:

Energy: 33 kWh/year · Cost: 8.32 €/year (0.69 €/month)

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.

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.
