1 EM3566 Introduction
1.1 Summary
The EM3566 is a single-board computer powered by a Rockchip RK3566 processor featuring four
ARM Cortex-A55 CPU cores and Mali-G52-2EE graphics and designed for AIoT applications such
as AI robot, smart POS machine, face recognition terminal, and business display integrated
equipment.
This SBC features 2GB memory (up to 8GB), comes with MIPI/LVDS, HDMI and eDP video out, and
offers Gigabit Ethernet port, as well as M.2 socket which enables expansion with a large hard drive
and plus a miniPCIe, a Nano SIM card socket for 4G cellular connectivity. Display and camera
capabilities with graphics and video hardware acceleration make it suitable for machine vision
applications. And built-in independent NPU, computing power of 0.8 TOPS for AI accelerator extend
the reach of AI solutions. EM3566 supports microphone array input, with high dynamic noise
reduction algorithm, it can accurately recognize human voices even in noisy environments, and
achieve precise voice control of the devices.
