Sipeed LicheeRV Nano: SOPHGO SG2002 Dev Boards with AI & Multimedia

Sipeed recently launched four Sipeed LicheeRV Nano boards powered by the SOPHGO SG2002 RISC-V CPU. These boards support 100Mbps Ethernet, Wi-Fi 6, an NPU, a camera, an LCD, and more.

The board is powered by the SOPHGO SG2002 RISC-V CPU, offering users a choice between a C906 RISC-V processor with speeds up to 1GHz or an Arm Cortex-A53. It also includes a RISC-V C906 co-processor that operates at up to 700MHz.

The LicheeRV Nano features a 1TOPS@INT8 NPU, 4MP camera support, and a MicroSD slot for AI vision projects. It also offers multimedia capabilities with MIPI CSI/DSI inputs for camera and display, plus audio enhancements via an onboard MEMS microphone and 1W speaker amplifier

The W/WE series of the LicheeRV Nano offers dual-band Wi-Fi 6, and BLE 5, and the 4E/WE series includes 100Mbps Ethernet. It features a USB 2.0 OTG Type-C and two 14-pin GPIO headers. The LicheeRV-Nano-WE model comes with all peripherals, including Mic, Wi-Fi/BT5, and Ethernet. Sipeed plans to add mainline Linux support to its SDK, enhancing the board’s utility with its 2Gbit memory for running basic Debian desktops, ideal for lightweight tasks, which is incredible. Thinking about running Linux on this board paves the way for multiple applications.
