4-in-1 KVM Switch HUB | TTL Serial Bluetooth Docking Station
Product Overview
The 4-in-1 KVM Switch is an all-in-one multi-device management solution designed for industrial control operation and maintenance, robotics R&D, and multi-platform development scenarios, eliminating the hassle of repeated peripheral plugging/unplugging, complex debugging adapters, and redundant peripherals when working with multiple embedded devices.Integrating KVM switching, 3-port USB 2.0 hub, UART/TTL dual serial debug ports, and master-slave integrated Bluetooth serial module, it supports both physical button and infrared remote switching, requires no driver installation, is fully compatible with Windows, macOS, Linux, and all mainstream embedded controllers (Raspberry Pi, Jetson, RDK series), allowing you to control multiple devices with a single set of keyboard and mouse, greatly improving work efficiency for dual-end development and server OPS scenarios.
Key Advantages
-
4-in-1 Multifunctional Design
Integrates KVM switch, 3-port USB 2.0 hub, UART/TTL dual serial debug ports and Bluetooth serial module into one device, eliminating the need for multiple separate adapters, saving desk space and reducing cabling clutter. Solves the pain point of needing multiple adapters for embedded development and robotic debugging.
-
Dual Switching Methods + Real-Time Status Indication
Supports one-click physical button switching with zero latency response, and high-sensitivity infrared remote control for long-distance operation without touching the device. Blue LED indicators clearly show the current active connection status, avoiding misoperation.
-
Dual Serial Debug Ports
Built-in UART debug serial port and TTL serial port allow direct connection to industrial control motherboards and robot main controllers for low-level debugging and firmware flashing, perfectly meeting the needs of hardware development and device debugging scenarios, no additional serial adapters required.
-
Wide Compatibility & Plug-and-Play
No driver installation required, fully compatible with Windows 7/8/10/11, macOS, Linux, Ubuntu systems, works with PC, Raspberry Pi series, NVIDIA Jetson series, RDK series and other Linux main controllers. Support Type-C independent power supply for high-load multi-peripheral scenarios, eliminating power shortage and device disconnection issues.
-
Master-Slave Bluetooth Serial Module
Integrated Bluetooth serial port supports wireless connection, getting rid of cable constraints, ideal for remote debugging and wireless control scenarios for ROS robots and mobile cars.
