Small, silent boards for walls, lobbies and media rooms.
Low-power fanless boards that fit in the wall, run quietly by a screen, and drive multi-display signage — with optional PoE to simplify wiring.
Application scenarios
Where a board disappears into the architecture and is expected to run silently for years.
Digital signage & media walls
Multi-display playback from a slim board. Compact 100-120mm NUC/NANO models drive 2-4 screens in portrait or landscape with no shelf space and no fan noise.
Building & smart-home control
A single small board runs light, HVAC and access logic. 8-bit GPIO plus RS-232/RS-485 connects sensors and controllers without an extra PLC or gateway box.
Home cinema & media centres
Quiet, low-power playback for media rooms and TV cabinets. A 15W Alder Lake-N board decodes 4K/8K media while a full ITX option adds PCIe for a capture card or GPU.
Pain points & how we solve them
Signage and smart-home gear live where noise, heat and cabling are visible.
Silence matters in the room
A whirring fan ruins a lobby or a living room. Fanless boards like AD742A run with no moving part, at low TDP, and stay quiet around the clock — no dust filter to clean either.
One cable is better than a nest
Wiring hides are expensive and break. Optional PoE (IEEE 802.3af, 48V/15W) lets you run data and power to a screen or sensor over a single Ethernet drop.
Multi-screen under one budget
Signage operators want many screens from one box. Small boards output multiple displays — HDMI, DP and Type-C — from a 100-120mm footprint that mounts behind any panel.
Tight enclosures, longer runs
Wall and cabinet mounts leave little room. Compact form factors from 100×72mm to 120×120mm plus wide-temp −20~+60℃ silicon keep it reliable in a sealed, warm wall cavity.
Recommended models & selection guide
Two compact, quiet options — pick by display count and whether you want PoE at the node.

Need more screens or PCIe?
For 8K media walls or a capture card, step up to an ITX or NUC board. Compare every model on the products page or shortlist with an engineer.
