Low-profile. Pro Performance.

Echo Express SEL Thunderbolt Expansion System

Compact, Desktop 1-slot Thunderbolt to PCIe Card Expansion System (for Low-profile PCIe Cards)

Connect a Low-profile PCIe Card

The latest ultra-light notebooks, small form factor, and all-in-one Mac, Windows and Linux computers with Thunderbolt™ ports are incredibly thin, but they lack PCIe card slots for upgrades. So, what if you want to add video capture, processing, or connectivity capabilities to your computer? Sonnet has the solution with Echo™ Express SEL. This compact desktop Thunderbolt expansion system lets you connect a low-profile PCIe card to your computer.

The Thunderbolt Interface Connection

Small and Mighty – when connected to one of your computer's Thunderbolt ports, Echo Express SEL allows you to connect a  low-profile PCIe card, such as Fibre Channel, Ethernet, video capture and processing, SAS and SATA host bus adapter, or a RAID controller.

Nearly Every Thunderbolt-compatible, Low-profile PCIe Card Supported

Echo Express SEL accommodates a wide variety of PCIe cards. Do you have a card in mind but aren’t sure it’s compatible? We’ve put together a compatibility list that identifies cards conforming to Thunderbolt technology requirements, and organized by fit and power compatibility with specific expansion systems.

Smart Design, Inside and Out: Aluminum Enclosure. Power On/Off.

With a shell crafted of rugged and lightweight aluminum, Echo Express SEL securely houses the installed PCIe card. Inside, the card is protected through the use of a variable-speed, temperature-controlled fan which ensures the card and chassis’ components remain reliably cool. The fan automatically speeds up as necessary to cool the card when it’s hot, and slows down when it’s cool. Since Echo Express products automatically power on and off with your computer, there is no power switch on the chassis, ensuring you don’t waste energy by forgetting to turn it off.

Designed for Low-profile PCIe Cards

Echo Express SEL supports one half-length (up to 6.6 inches long), low-profile, single-width PCIe card; PCIe 4.0, 3.0, 2.0, and 1.1 PCIe 4.0 cards are supported. Many of the most popular Thunderbolt-compatible high-speed networking and storage controller cards are a perfect fit, and even the BlueFish 444 Epoch 4K Neutron video card can be accommodated.

Quiet Please

Echo Express SEL is designed to be ultra-quiet so that it can be comfortably used in noise-sensitive environments. The airflow path within the chassis has been specially designed to enable the fan to quietly and efficiently cool the installed card at all times, even during peak operation.

Secure Connections for High Performance

Thunderbolt Cable and ThunderLok Included. Sonnet includes a Thunderbolt cable that supports Thunderbolt’s maximum bandwidth and is fully compatible with Thunderbolt 5, 4, and 3 computers. Sonnet also provides ThunderLok, a Thunderbolt connector cable lock, that prevents accidental cable disconnections.

ThunderLok Advantage: Many Sonnet Thunderbolt products featuring Thunderbolt ports come equipped with threaded mounting holes to securely attach a Sonnet ThunderLok connector lock, preventing Thunderbolt cables from accidentally disconnecting.

Thunderbolt Technology: Fastest External Interface Available

Sonnet Thunderbolt products feature a high-speed Thunderbolt interface that delivers PCIe bandwidth needed to support data transfers at full speed.

Connect Additional Thunderbolt Devices. One port is reserved for connecting to your computer; the second port enables connection of additional Thunderbolt peripheral devices in a daisy chain.

10 Gbps USB 3.2 Gen 2 Support. 10 Gbps USB 3.2 Gen 2 support allows you to connect a USB device to the second Thunderbolt port using the proper cable or adapter.

Provides 15W of Power. For peripherals requiring extra power, 15 watts is provided to bus-powered devices through the secondary Thunderbolt port.

Supports Connecting Up to One 8K Display. Maximize the utilization of one computer Thunderbolt port, connecting the largest display supported by your computer.

Designed for the Fastest Connection to Thunderbolt Computers

Echo III Desktop is purposely designed with a Thunderbolt 3 controller and its four lanes of PCIe (not available in a Thunderbolt 4 peripheral) to achieve maximum simultaneous ingest speeds. Watch this video to learn more about the performance benefits.
