Features & Specifications | Openterface KVM-Go Series

Pre-Launch Status

The KVM-Go Series is currently in pre-launch development. We're refining the PCB and case designs. Join our waiting list to stay updated on progress and get early access.

Note: Features, specifications, and design are still subject to change as development continues.

Product Models

KVM-Go HDMI Male — Direct HDMI connection
KVM-Go DisplayPort Male — High-performance DisplayPort
KVM-Go VGA Male — Legacy system support (in development)

Core Features

Ultra-Compact Design

Keychain-sized form factor that fits in your pocket. No more carrying bulky KVM devices or searching for video cables.

Built-in Video Connectors

Direct plug-in capability with built-in male connectors:

HDMI Male — Modern device compatibility
DisplayPort Male — High-performance support
VGA Male — Legacy system support (coming soon)

BIOS-Level Access

Direct access to target device BIOS, firmware, and startup management without network dependencies.

Network Independence & Lightning-Fast Response

Stable headless control using built-in video capture and emulated keyboard/mouse (HID) input. No network connection required. Hardware startup time is less than 1 second, ensuring immediate troubleshooting without workflow delays.

Upgraded Video Performance

Massive upgrade from Mini-KVM's 1080p@30Hz:

Input: 4096×2160 @ 60 Hz (YUV420), 4096×2160 @ 30 Hz (YUV444)
Output: 4096×2160 @ 60 Hz (MJPEG), 3840×2160 @ 30 Hz (YUV420)
Default: 1080p@60Hz for optimal stability and performance
4K Mode: Available as experimental feature*
Compression: YUV420, YUV444, and MJPEG support

*Note: 4K mode generates additional heat; device surface may become quite hot during extended operation

MicroSD Slot

File transfer between host and target devices

Cross-Platform Support

Host apps compatible with macOS, Windows, Linux, Android, and Chrome web app for universal integration.

Text Transfer

Effortlessly transmit text by simulating keystrokes—perfect for usernames, passwords, and code snippets. Supports ASCII characters including symbols and punctuation.

Host → Target: Send text via emulated keyboard strokes
Target → Host: Copy text from target's screen to host via OCR (macOS only)

Text Transfer Limitations

No Clipboard Integration: Only emulates typing, no image or document transfer
ASCII Only: Limited to ASCII characters (no Chinese, Japanese, Korean, etc. support)
Length Considerations: Best for short text; large blocks may cause performance issues
OCR Feature: Target → Host text transfer currently only available on macOS

Plug-and-Play Convenience

No software installation required on target device. Control begins immediately upon connection with no software traces left behind.

Audio Integration

HDMI embedded audio passthrough for complete multimedia experience. (Not supported on KVM-Go VGA; pending confirmation for KVM-Go DP.)

Bluetooth Capability

Built-in Bluetooth support enables native iPadOS app functionality (coming soon), making KVM-GO one of the few KVMs that works natively with iPads.

Open-Source

Fully open-source hardware and software for transparency and community innovation.
