The Sonnet Echo Express SEL Thunderbolt 3 Expansion System (ECHO-EXP-SEL-T3) is a compact one-slot Thunderbolt-to-PCIe chassis for professional low-profile PCIe cards.
The SEL provides one x8 mechanical, x4 electrical PCIe 3.0 slot for a compatible low-profile card, making it ideal for compact video capture, audio, storage or networking expansion.
Two Thunderbolt ports provide a host connection plus downstream daisy-chain support. Although this model uses a Thunderbolt 3 controller, Sonnet's current compatibility documentation supports suitable modern Thunderbolt 5, Thunderbolt 4 and USB4 hosts.
The enclosure's small footprint makes it well suited to mobile workstations, DIT carts and desktop installations where only one specialist PCIe card is required.
A universal 60W external power adapter supplies the installed card, while the variable-speed cooling system manages airflow without the size and noise of a larger multi-slot chassis.
Sonnet currently lists ECHO-EXP-SEL-T3 as End Of Life (EOL). The newer Thunderbolt 5 replacement is ECHO-EXP-SEL-T5.
