DFRobot - Thunderbolt 4 10G Ethernet Adapter for LattePanda Sigma (40Gbps)

This Thunderbolt 4 10G Ethernet adapter adds high-speed wired networking to USB4 and Thunderbolt host systems through a 40Gbps Type-C bus and native 10GBASE-T Ethernet interface. Designed for LattePanda Sigma, high-performance single-board computers and other compatible host devices, this external 10G network adapter provides up to 10Gbps Ethernet connectivity through a standard RJ45 port.

40Gbps USB4 and Thunderbolt 3/4 Host Interface

This 10GbE adapter uses the JHL6340 Thunderbolt chip and provides a theoretical Type-C bus bandwidth of up to 40Gbps. Compatibility with USB4 and Thunderbolt 3/4 allows the adapter to connect to supported desktop terminals, mobile computing devices and high-performance embedded computers through a high-bandwidth external interface.

Native 10GBASE-T Ethernet Through Standard RJ45

This Thunderbolt Ethernet adapter integrates an AQC107 network controller and provides a standard RJ45 interface with a transmission rate of up to 10Gbps. The Ethernet interface also supports adaptive compatibility with Gigabit and 100Mbps networks, allowing the same adapter to operate across different wired network infrastructures. CAT6 or higher specification network cable is required.

Active Cooling for Sustained High-Throughput Networking

This 10G Ethernet adapter combines an all-metal enclosure, multi-dimensional heat dissipation vents and an internal cooling fan. The active thermal design helps reduce heat accumulation during continuous high-throughput network transfers and supports stable link operation under sustained loads.

Integrated Network and Activity Status Indicators

This external network card integrates status indicators at the RJ45 interface for direct visibility of network link and data activity. The indicators provide at-a-glance feedback during setup, troubleshooting and continuous network operation.
