EM3326S is a single board computer (SBC) powered by Rockchip RK3326-S Quad-core ARM Cortex-A35 processor that offers one of the best cost/performance ratios on the market with Camera, WiFi&BT and 4G LTE Model and specially designed for smart audio device.
RK3326-S supports almost full-format H.264/H.265 decoder by 1080p@60fps, H.264 encoder by 1080p@30fps, high-quality JPEG encoder/decoder. Embedded ARM G31-2EE GPU makes RK3326-S completely compatible with OpenGL ES 1.1/2.0/3.2, DirectX 11 FL9_3, OpenCL 2.0 and Vulkan 1.0. Special 2D hardware engine will maximize display performance and provide very smoothly operation.
The SBC is comprised of a soldered-on CM3326S system-on-module (SOM) and a carrier board with a microSD slot, Ethernet port, two USB2.0 Host, LVDS/MIPI-DSI, RGB LCD and MIPI CSI interfaces.
