The Sipeed NanoKVM-USB is a compact and cost-effective KVM device featuring Target USB and Host USB interfaces, along with USB 2.0, USB 3.0, and 4K HDMI ports. This finger-sized USB tool provides a convenient solution for operations and multi-device collaboration, enabling users to remotely control a host device—such as a computer, server, or SBC—down to the BIOS level, including power on/off functionality.

The NanoKVM USB enables users to perform maintenance tasks without requiring a keyboard, mouse, or monitor. With just a single computer and no need for additional software downloads, users can initiate graphical operations directly through the Chrome browser, provided the browser version is 89 or higher.

Previously, we covered the Openterface Mini-KVM and Pi-Cast KVM. The Openterface Mini-KVM provides a straightforward solution for managing headless devices such as mini PCs, kiosks, or servers directly from a laptop or desktop. Meanwhile, the Pi-Cast KVM, a Raspberry Pi CM4-based solution, enables users to remotely control and manage multiple devices regardless of their operating systems. Feel free to check them out if you’re interested in these products.
