NanoKVM is a series of compact, open-source IP-KVM devices based on the LicheeRV Nano (RISC-V). It lets you remotely access and control computers as if you were sitting in front of them, making it useful for servers, embedded systems, and other headless machines.
Choose the NanoKVM model that best fits your deployment:
- NanoKVM-Cube Lite: A barebones kit for DIY users and bulk deployments.
- NanoKVM-Cube Full: A ready-to-use kit with a case, accessories, and a pre-flashed system SD card.
- NanoKVM-PCIe: A PCIe-bracket form factor for internal chassis mounting. It draws power from the PCIe slot and supports optional Wi-Fi and PoE.
- NanoKVM-Pro: A higher-performance version with major upgrades:
- Resolution: Up to 4K@30fps / 2K@60fps.
- Network: 1Gbps Ethernet + PoE + Wi-Fi 6, upgraded from 100Mbps Ethernet.
- Latency: Hardware-accelerated encoding reduces latency from 100-150ms to 50-100ms.

Start with the guide that matches the part of NanoKVM you want to work on:
- System support modules: Build and update the low-level hardware support components in support/sg2002/README.md.
- Backend service: Set up, build, and understand the Go service in server/README.md.
- Frontend UI: Develop, lint, and build the React interface in web/README.md.
Backend compilation and runtime validation require the target toolchain or a NanoKVM device. See the module-specific guides above for the latest development workflow.
NanoKVM is based on Sipeed LicheeRV Nano. You can find specifications, schematics, and dimensional drawings in the download station.
The NanoKVM Cube/PCIe hardware is built from these components:
- NanoKVM Lite: LicheeRV Nano plus the HDMI-to-CSI board.
- NanoKVM Full: NanoKVM Lite plus the NanoKVM-A/B boards and enclosure.
- HDMI-to-CSI board: Converts the HDMI input signal.
- NanoKVM-A board: Provides OLED, ATX control output through USB-C, auxiliary power, and physical ATX power/reset buttons.
- NanoKVM-B board: Connects NanoKVM-A to the host computer's ATX pins for remote power control.
The NanoKVM image is built with the LicheeRV Nano SDK and MaixCDK. It is intended for NanoKVM hardware and is not a general-purpose KVM software package for other LicheeRV Nano or SG2002 products. If you want to build an HDMI input application on LicheeRV Nano or MaixCam, please contact us for technical support.
Note: Of the 256MB memory on SG2002, 158MB is currently allocated to the multimedia subsystem for video capture and processing.
