Why Choose the HD-352C Digital Signage Mainboard

Quad-Core Chip for Stable, Reliable Performance

Powered by the Hi3751V352 quad-core chip running at 1GHz, the HD-352C delivers stable and reliable performance for continuous commercial use. This quad-core architecture handles 1080P image display smoothly, making it a dependable choice for digital signage and advertising players.

Four-Layer Board Design for Greater Durability

The HD-352C adopts a 4-layer PCB design, delivering stronger stability and durability than typical 2-layer alternatives. This improved board design puts it far ahead of similar products in the industry, extending lifespan and reducing failure rates in demanding deployments.

HDMI Input for More Expansion

With 1× onboard HDMI input, the HD-352C makes it easy to connect laptops, media players, and other expansion devices. This flexibility meets the needs of a wide variety of scenarios — from meeting rooms and retail displays to hospitality and education.

Unattended, Less to Worry About

The board supports a hardware watchdog function, enabling true unattended 7×24 operation. If the system ever freezes, the watchdog automatically restarts it — minimizing downtime and eliminating the need for on-site maintenance.

Wireless Management, Operate Easily

No server installation required. The HD-352C supports point-to-point wireless messaging via smartphone, so you can update content and manage displays quickly and easily from a mobile device.
