Upgraded Sipeed NanoKVM-USB USB KVM solution gains 4K 60 FPS video capture and HDMI loop output

Sipeed has released a new variant of its NanoKVM-USB low-cost USB KVM adapter, which upgrades 2K 30 FPS capture and 4Kp30 loop out to 4K 60 FPS capture and 4Kp60 HDMI loop output. The new NanoKVM-USB 4K keeps the same ports as the earlier model, with HDMI and USB-C inputs connected to the target, and another USB-C port that connects to the host, in order to remotely control the target with keyboard, mouse, and monitor emulation. A USB Type-A port that can switch between host and target modes is also implemented, for instance, to share a USB drive between the two systems. NanoKVM USB 4K specifications: Video Input/Output HDMI input up to 4Kp60 from target device HDMI loop output up to 4Kp60 for optional connection to a monitor USB USB Type-C port for connection to the target device for keyboard/mouse emulation USB 3.0 Type-C port for connection to the host […]

Sipeed NanoKVM-USB low-cost USB KVM solution works with Google Chrome or other compatible web browsers

Sipeed NanoKVM-USB is an inexpensive and tiny full HD USB KVM solution with HDMI and USB-C inputs connected to the target, and another USB-C port that connects to the host remotely controlling the target with keyboard, mouse, and monitor emulation. The NanoKVM-USB also features a USB Type-A port that can be switched between host and target modes, for instance, to share a USB drive between the two computers. That’s the third KVM solution from Sipeed after the original NanoKVM KVM-over-IP cube relying on Ethernet connectivity to the host and the NanoKVM-PCIe that takes its power from a PCIe slot in the target machine while using Ethernet or WiFi 6 for connectivity to the host machine. The NanoKVM-USB does without Ethernet or WiFi and instead relies on USB to control additional machines with a single keyboard, mouse, and monitor – or laptop – shared between the host and the target(s). NanoKVM […]
