IP KVM questions
What can I control with the USBridge IP KVM?
Any device with a video output that accepts USB keyboard, mouse or gamepad input: PCs, servers, mini PCs and single-board computers. The KVM captures the HDMI picture and acts as the USB keyboard, mouse or gamepad toward the target, and any other USB device can be passed through. With a flashed NanoKVM it also works as a game streamer for consoles.
Is USBridge an IP KVM (KVM over IP)?
Yes. It gives BIOS and UEFI access, ISO and IMG virtual media, immutable Btrfs snapshots and remote control over the network, with Tailscale peer-to-peer access and no port forwarding. On top of that it streams games and passes through gamepads and any USB device.
Can I stream games through the KVM?
Yes. USBridge is the first hardware Moonlight streamer. Every supported device, the ready KVM 2.0 or a flashed Radxa Zero 3W, Radxa Cubie A7Z or Sipeed NanoKVM, works as a hardware streamer: 1080p at 60 FPS without lag, with audio, Sunshine and Moonlight compatible. The stock Moonlight client on a PC, Mac, phone, tablet or TV connects to it, and the source, a PC or a game console, needs no software.
Which boards does the firmware support?
Radxa Zero 3W, Radxa Cubie A7Z and the Sipeed NanoKVM (SG2002). A ready KVM 2.0 is available from $90 (board, heatsink and HDMI capture) and from $139 as a full kit with screen and case; prices exclude tax and shipping.
