Yepkit USB 3.1 Switchable Hub

Being able to connect/disconnect USB devices without 
having to physically plug/unplug is quite helpful for 
recurrent processes. Bellow are some example of use 
cases where this capability is quite advantageous: 

The control is achieved by sending UP/ON and DOWN/OFF commands to the on-board microcontroller, visible to the 
host system as an HID USB device. The commands are based in a very simple protocol detailed in Control Protocol 
section of this manual. 

Key Features:

Three USB 3.1 Gen1 downstream ports

Selectable USB bus powered or Self/Externally powered

Full downstream ports switching (both VBUS power and data lines)

ICSP programming interface for loading new firmwares

Loaded with a Bootloader for firmware updates/programming through USB

Key Benefits:

Full control over your USB device ON/OFF

Remote switching of USB devices

Bus powered for ease of use

Self/Externally powered for higher current devices

High flexibility of use and integration brought by a user application layer control software

Open source control software allowing customization

High speed of USB 3.1 Gen1

Data backup systems using USB HDDs

Data access control by emulating the physical plug/unplug by connecting/disconnecting the USB device (Both 
power and data lines) containing or relaying the data

Power saving schemes for solutions with USB powered systems or devices
