1. Overview

1.1 Summary

The Compact3588S is a credit-card-sized single-board computer (SBC) with a layout similar to the Raspberry Pi 4, but based on a more powerful 64-bit octa-core Rockchip RK3588S processor. Featuring quad-core Cortex-A76 and Cortex-A55 CPUs, a Mali-G610 MC4 GPU, and a 6 TOPS NPU, it delivers efficient performance across a variety of computing tasks. It supports up to 16 GB of RAM and 256 GB of eMMC storage, and includes an M.2 slot for high-speed storage expansion. The Compact3588S offers multiple video output options, including HDMI, DP-to-HDMI, and MIPI LCD, supporting triple-display setups (e.g., 8K+4K+2K) or single-display output up to 8K. It is well-suited for scenarios requiring high-performance computing and complex processing capabilities, such as edge computing, artificial intelligence, intelligent security, industrial control, and machine vision.
