Specifications
Components
Dual-core C906 RISC-V processor at 1GHz + 700MHz with integrated TPU, supporting Linux and RTOS simultaneously
Integrated tensor processing unit delivering 0.5 TOPS at INT8 precision for edge AI inference
Bus Interfaces
The Milk-V Duo is one of the smallest and most affordable RISC-V development boards available, measuring just 21mm x 51mm. Powered by the CVITEK CV1800B SoC (or SG2002 in the 256M variant), it features dual RISC-V C906 cores and can run Linux and RTOS simultaneously on separate cores, making it ideal for embedded and IoT applications.
Despite its tiny size, the Duo packs a 0.5 TOPS INT8 TPU for edge AI inference, 100Mbps Ethernet, a MIPI CSI camera interface, and up to 26 GPIO pins with Raspberry Pi-compatible pinout. The Duo 256M variant upgrades to 256MB RAM and adds an ARM Cortex-A53 core, allowing seamless switching between RISC-V and ARM architectures.
All chip data and board designs are fully open-source, with active community support through the Milk-V GitHub organization. The board supports buildroot and Debian-based Linux distributions, Arduino development, and the CVITEK TDL SDK for AI model deployment.
