Overview
The Milk-V Duo S is an upgraded Milk-V Duo featuring the Sophgo SG2000 controller with 512 MB of memory and expanded I/O. Dual RISC-V C906 cores run at up to 1 GHz with an optional Cortex-A53, and boot mode can be switched between RISC-V and Arm via a hardware switch.
A 0.5 TOPS INT8 TPU, dual MIPI CSI cameras with ISP, onboard Wi-Fi 6 / BT 5, 100 Mbps Ethernet with PoE support and MIPI DSI output make it a compact platform for AI vision and embedded Linux/RTOS work at an entry-level price.
Key Benefits
Dual-architecture RISC-V/Arm flexibility with a 0.5 TOPS TPU in a 43 × 43 mm board — the cheapest route to dual-camera AI vision with Linux + RTOS concurrency and an open-source SDK.
Applications
AI camera nodes, embedded vision and imaging, industrial control with RTOS real-time loops, smart home devices, robotics and education.
