On macOS, pressing F11 shows the macOS desktop instead of passing the F11 key to the app and the target computer. To fix this, you can unbind F11 from the "Show Desktop" function. Here’s how:
Yes, the Openterface Mini-KVM includes a switchable USB-A port shared between the host and target devices. With a USB stick/disk plugged into this port, files can be transferred between host and target by following these steps:
This method can also be used in the opposite direction.
The current design does not support toggling at the software level; it can only be physically flipped for now.
Implementing toggling at the software level would necessitate a new design, incorporating a button and an LED indicator (either green/blue or on/off) to signify whether the USB port is set to the host or target mode.
Additionally, this would require the integration of an additional chip, leading to increased costs in both hardware and software development. The existing design represents a compromise, aimed at balancing cost-efficiency and basic functionality. Despite the potential for increased costs, we are interested in incorporating this feature in a future version for better user experience.
USB 2.0 is fully capable of handling video capture at 1080p@30Hz, transmitting HID signals (for keyboard and mouse), and managing standard-speed file transfers between the target and host computers. This makes our product a speedy, lightweight, and portable solution, exactly as designed.
Using USB 3.0 would make the PCB design much more complex and significantly increase production costs. Additionally, while USB 3.0 does offer faster file transfers, it also generates more heat, which could shorten the lifespan of the device.
We are considering the application of USB 3.0 for the next version, targeting more professional use scenarios and stationary KVM solutions.
Yes! We will open source both hardware and software. Just bear with us a little longer; We need to tidy quite some things up for opening up. If you are interested in contributing, please do tell us via this email: info@techxartisan.com. Stay tuned!
Yes, the direct connection of the Openterface Mini-KVM enables access to low-level BIOS or firmware settings.
This feature stands in contrast to software-based KVM solutions or remote control applications like TeamViewer and Zoom, which are typically not capable of BIOS-level interactions.
It seems that some old computers’ BIOS can’t recognize our device’s USB hub, which can cause issues with our emulated keyboard and mouse not working properly at the BIOS level. We’re keeping an eye on this problem.
We’ve had a report that on one specific HP computer, the HP Engage Flex Pro, the keyboard doesn’t work at the BIOS screen, though it functions normally once the operating system boots up.
If you encounter the same issue, please report it to us via a GitHub issue.
Video data is captured via HDMI and transmitted over USB 2.0 to the host computer for display. The switchable USB 2.0 port allows USB drive or other USB device sharing between the target and the host.
The device does not require an external power supply, as it is designed to be powered through its USB Type-C connections from the host, enhancing its portability. In scenarios where the target device is a low-power micro-computer, such as a Raspberry Pi, it could be powered through the host via the Mini-KVM’s switchable USB port. However, this is not recommended. The standard method of operation is to have an external power supply to the target device.

No. We are aware that there are still many old headless computers out there that require PS/2 keyboards and mice. As far as we know, there isn’t yet an elegant solution for converting USB HID signals to split into PS/2 keyboard and mouse signals. We are still investigating this matter and considering how to support PS/2 in future versions of the Mini-KVM. If you know of any solutions that could elegantly work with our Mini-KVM, please share them with us. Thank you!
Yes, you can! Our Mini-KVM can technically handle this, but we’re still tweaking the code and running tests. We’re focusing on making sure that our software can automatically link up the keyboard and mouse with the right video source when you use more than one Mini-KVM at a time. Also, we’re sprucing up the software’s UI to make it better for this kind of setup. Stay tuned to our community updates for when we roll out this feature!
Our device doesn’t support ATX (power on/off control for the target computer). We designed it to be portable, quick for troubleshooting, and stable for local control. It’s really meant to be used when you’re right there with your laptop, managing one or several target computers. We may build a pro version in the future with ATX and more features.
Our device handles 1080p video with under 140 milliseconds of latency, making your control experience smooth and seamless.
The current design focuses on technical and IT operations, providing reliable control for device configuration and troubleshooting rather than high-resolution gaming. While it’s great for many tasks, this mini-KVM might not meet the display needs of high-quality gaming.
We know a lot of you are looking for top-notch display features. While it’s not our main focus right now, based on your feedback, we’re considering adding enhanced display capabilities in a professional version of the Openterface Mini-KVM.
The Openterface Mini-KVM has been engineered to ensure reliable and stable performance through wired connections, using HDMI and USB. While it is technically feasible to stream video over a network via our host applications, we are considering adding a VLC, and even VNC feature to our host applications in the future.
Sort of. The Openterface Mini-KVM captures video through an HDMI port. However, you can use various video adapters like VGA-to-HDMI, DVI-to-HDMI, miniHDMI-to-HDMI, or DP-to-HDMI, to connect different video sources.
Absolutely! There are loads of ways you can chip in:

Our ultimate goal is to enable AI to control target computers, and the Openterface plays a crucial role in this vision. Inspired by projects like OthersideAI’s self-operating computer, we aim for the mini-KVM to act as an extension of the ‘hands’ (providing keyboard and mouse control) and ‘eyes’ (capturing the video source) for the host computer. If the host computer is powerful enough, it could potentially emulate the capabilities seen in the 2013 movie "Her". While this is a future aspiration, it highlights the exciting possibilities we see for the mini-KVM.
