Turris MOX B (Extension)
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 complete Turris MOX 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 B (Extension) module
With MOX B, you can add more hardware to your configuration. It includes an mPCIe slot for a compatible Wi-Fi card, a hard drive controller, or an LTE modem. If you install an LTE modem, the MOX B has a SIM card slot that you can use. If you are using Wi-Fi networks, we recommend using the original MOX Wi-Fi Add-On (mPCIe), which offers significantly higher speeds than SDIO Wi-Fi.

Compatibility
The configuration can only contain one MOX B module. The PCIe bus is terminated there. For this reason, the MOX B cannot be combined with MOX F. If you need a module with the same parameters but with PCIe signal, choose MOX G. This module can only be used as an extension in a set. You need at least MOX Start. MOX B is included in the MOX Power Wi-Fi and MOX Classic sets. When combining it with other modules, ensure that they are compatible.
External connections: 1x SIM card slot.
