Openterface KVM extension card
Plug-and-play KVM: HDMI capture in and USB HID out, so the console becomes a portable crash cart for headless machines.
What it takes
- Plug & play
- Purchase required
- Software only
Difficulty 1 of 3 — easy.
Details
TechxArtisan's card slots into the expansion port and, with the open-source Openterface_QT app, shows another machine's video while your keyboard and trackball act as its keyboard and mouse — BIOS included. Version 1.1 adds a switched USB-A port and a USB-C port that lets the uConsole keyboard type on other machines. Hardware is open source on GitHub.
