EC-A3399C is a six-core mini embedded computer based on the high-performance, open-source AIO-3399C platform. It is powered by the 64-bit Rockchip RK3399 processor, which combines two Cortex-A72 cores with four Cortex-A53 cores and runs at up to 2.0 GHz. The computer features an industrial aluminum-alloy enclosure, a fanless cooling system, stable long-term operation, and a rich set of expansion interfaces.

EC-A3399C supports hardware decoding of H.265/HEVC and VP9, H.264 encoding, 4K HDR, and hardware decoding at up to 4K. It supports HDMI 2.0, DisplayPort 1.2, and other display outputs, with mirrored or extended dual-display configurations. Typical applications include gaming equipment, digital signage, vending machines, and robotics.
