Kvm
This project provides KVM over IP hardware and software for remote computer management. It functions as an ATX power management controller, a remote serial console server, and a virtual media emulator. A WebRTC remote access gateway is used to bypass NAT and firewalls for low-latency hardware control via a web browser.
The system is distinguished by its ability to simulate physical peripherals at the hardware level, including HID device emulation for keyboard and mouse input and USB mass storage emulation for streaming ISO images. It features a UART-to-web bridge for remote serial console access and utilizes H.264 hardware encoding for high-definition video streaming.
The platform covers broad capability areas including power state control for ATX and DC systems, NAT traversal and cloud-based connectivity, and firmware management. It also supports hardware extensibility through dedicated pins for custom module development and provides 3D design files for physical modifications.
System configuration and administrative tasks are handled through a web interface or secure SSH access using public key authentication.
