The HYY-051D uses the Rockchip RK3566 quad-core processor at up to 1.8 GHz with a 1 TOPS NPU, 2 GB memory and 32 GB eMMC as standard, and decodes 4K@60fps H.265/H.264. HDMI, eDP, LVDS and MIPI outputs, Gigabit Ethernet and Wi-Fi/BT keep power and cost down — a practical choice for entry-level signage and kiosks deployed in volume.
