## Description

The Milk-V Duo S is an upgraded version of the Duo, built around the SG2000 SoC which combines dual RISC-V C906 cores with an ARM Cortex-A53 core. A hardware switch allows selecting between RISC-V and ARM boot modes, and the board can run Linux and RTOS simultaneously on separate cores.\n\nWith 512MB SIP DRAM, dual MIPI CSI camera interfaces (2-lane each), optional onboard WiFi 6 and Bluetooth 5, and 39 GPIO pins across two 26-pin headers, the Duo S is significantly more capable than the original Duo while maintaining a compact 43x43mm footprint. It also supports eMMC storage, PoE via HAT, and MIPI DSI display output through the GPIO header.\n\nThe 0.5 TOPS INT8 TPU enables on-device AI inference, and the board is supported by the CVITEK TDL SDK and TPU SDK for model deployment. The Duo S is ideal for computer vision projects, IoT gateways, and embedded AI applications where wireless connectivity and dual camera support are needed.
