LeafKVM has entered crowdfunding on Crowd Supply following its earlier pre-launch coverage, introducing a revised hardware configuration while maintaining its focus as a compact, self-contained KVM-over-IP device. The system provides remote keyboard, video, and mouse access to computers, servers, and other HDMI sources without requiring software on the target machine.
