The Milk-V Duo and Duo 256 are single-board computers based on the CV1800B and SG2002 RISC-V SoCs, respectively. They provide up to 26 GPIO (some have dual functions) and provide silicon for edge intelligent monitoring projects and other AIoT applications. They have an identical footprint to the Raspberry Pi Pico but are actually single-board computers so have more in common with the Pi Zero in that they can run Linux or RTOS. There is no video out, however.

There are pads to add an Ethernet connection but the board also supports RNDIS networking (Ethernet over USB). The Duo and Duo 256 both contain two C906 CPUs, one clocked at 1 GHz, the other at 700 MHz while the Due 256 also has an ARM Cortex-A53 at 1 GHz. They both incorporate a 16P 0.5 mm pitch FFC connector for attachment of a camera and a microSD card slot.

The Duo 256 has four times as much RAM, a twice as fast tensor processing unit and accepts a slightly faster/higher resolution camera input. See the below table for additional comparisons.

The CAM-GC2083 2MP (1920x1080) 30fps CMOS camera module is also available and compatible with both development boards.
