Pegasus Astro USB Control Hub

Lack of a trusty USB3.1 Hub in astrophotography market, triggered Pegasus Astro to develop a USB3 Hub controller which will be also able to switch ON/OFF each USB port.

We proudly present the Pegasus Astro – USB Control Hub (in short UCH):

A SuperSpeed (SS), low power, switchable USB3.1 Gen1 hub and fully compliant with USB-IF’s USB 3.1 Gen1 specification . The Hub supports Hi-Speed (HS), Full Speed (FS) and Low Speed (LS). The new SuperSpeed hubs operate in parallel with the USB 2.0 controller, so 5 Gbps SuperSpeed data transfers are not affected by slower USB 2.0 traffic.


  • 6x USB 3.1 Powered Ports
  • Industrial Grade Temperature Support
  • Switchable USB Ports
  • High Quality, Robust Aluminium Enclosure
  • 12v DC Operation
  • Expansion Port (EXT)

6 x USB3.1 Active Ports

The device has 6 x USB 3.1 Ports. All ports are backward compatible with USB 1.0 and USB 2.0 devices.

Each port can deliver up to 2.5Amps of current. There is a smart current limit sensor in every port which automatically limits or cuts power in case of a short-wire or power consumption that is above 2.5Amps.

Each port is monitored by the USB Controller and in case of a current limit, it triggers a warning pop up in the operating system.

Industrial grade temperature support

Four powerful Smart Mosfet transistors provide “electric juice” to your precious equipment. Sophisticated short circuit and overload per port protections cut the power and report the incident into our software. Every Mosfet is capable to provide up to 7Amps of current.

Metal & good quality output sockets ensure that will provide all the juice you need and can secure in place your extension power cables

Built-in Power Sensors

A precise voltmeter and an amp meter (can measure up to 20A) measure and display in real-time your power input. If the input is more than 14.5V the power is instantly cut off to protect your equipment.

Individual Current Meter per 12V port and Dew Heaters

Every 12V output and every Dew Heater Channel has an internal and independent digital current meter. You can view each port’s power consumption in the software.

Other Key Features

Aluminium Enclosure

A high quality robust, blue anodised aluminium enclosure houses the electronics of the USB Hub. The metal enclosure designed and tested to survive ±5kV ESD strikes

Switchable USB Ports

Each USB port can be controlled and switched ON/OFF by our standalone software. (power + data). You are going to love this feature. No more pull out and re-plug USB cables of your equipment.

12V DC Operation

The 12V DC operation was our first design requirement. As most of your astro-equipment requires 12V DC why to use something different? Hub accepts 12-14V of operation. This means that you can plug unregulated 12V power from a battery.

Expansion Port (EXT)

A RJ12 external ports allows future device expansion

Supported By


Device fully supports ASCOM switch. This means that you can switch ON/OFF each USB port via ASCOM supported software.


USB Control Hub is fully supported by Indilib framework

Standalone Software

Switch ON/OFF USB Ports on demand. Monitor USB Voltage levels. Easily name each USB port based on the device that is attached on it.


Unity Platform Support

Pegasus Astro Unity Platform is their new all around application. Our goal is to provide a robust and modern application that is going to support current and future products under one roof.

A modern frontend allows the full control of all Pegasus Astro devices.

Moreover, a REST JSON api helps developers from 3rd party software to interact with our products.

Almost Perfect
Monday, 15 August 2022  | 

It was time to move away from flakey USB hubs purchased on Amazon and buy this. The Pegasus Astro USB Control Hub is a powered USB switch, with 6 x USB 3.1 ports in a rugged metal case. If you need to run devices at full 3.1 speed with power, outside, then this box is perfect, or almost. There are some things to be aware of... Firstly, it is powered, and without DC power it is a brick that does nothing, it won't even allow unpowered USB 2 devices to talk. So lesson 1 is buy this with a suitable 12v supply as extra (and the Pegasus Astro PSU can drive it at 10amps, which is more than enough). The second lesson is that this needs ASCOM 6.6 on your laptop if you want to manage it, so you might need to upgrade your software too. I did, it only took a minute, and I'm really pleased to say that not only does the custom Pegasus Astro software work but also NINA does too. NINA can monitor all 6 ports, turn them on and off, and report their power draw. Nice. The final lesson is that mounting this unit to your rig could be better - there are two tiny holes in the base, barely big enough for anything. I would love to see four standard side threaded holes to bolts. So the only practical way to mount it is with either Velco or cable ties.
