Turris Mox E

Turris MOX E (Super Ethernet)
The Turris MOX is a unique modular router designed for small and medium-sized businesses, computer enthusiasts, and households that are aware of the risks of the internet. Thanks to its secure default configuration, automatic firmware updates, and an adaptive distributed firewall, the product is very secure. The Turris MOX is also open source - it runs a free Linux operating system (based on OpenWrt) on open hardware. You can purchase a Turris MOX as a complete set (Pocket Wi-Fi, Power Wi-Fi, and Classic) or build your own. For this, you need the MOX Start base set, which you can expand with one or more modules (MOX B, C, D, E, F, and G) and add-ons (MOX Wi-Fi Add-On (SDIO), MOX Wi-Fi Add-On (mPCIe), and MOX PoE Add-On).

Main features of the MOX E module (Super Ethernet)
The MOX E module is an ideal choice if you need more Ethernet ports to connect devices to your network. It is twice as wide as the other modules and includes a managed switch with eight ports for gigabit Ethernet.

Compatibility
Unlike the MOX C module, the SGMII bus in the MOX E module is not terminated, allowing up to three MOX E modules to be connected in series. This module can only be used as an extension in a set. You need at least the MOX Start. If you combine it with other modules, make sure they are compatible.
