MikroTik RB14eU Professional miniPCI-e Adapter for Wireless & LTE Integration

RB14eU is a PCIe adapter designed for expanding the wireless and mobile connectivity of a desktop computer or server, enabling simultaneous installation of four miniPCIe cards into a single standard PCIe slot. It is commonly used in network infrastructures where integrating MikroTik R11e wireless interfaces into existing PC hardware is required, eliminating the need for additional dedicated equipment.

The adapter features four independent miniPCIe slots, each with a dedicated SIM slot for separate 3G/LTE connectivity per channel. Four USB ports provide the necessary host connectivity for mobile cards, while the USB Power Reset function enables controlled interface restarts — essential for remote management scenarios. Hardware reliability is backed by an MTBF of 100,000 hours, suitable for continuous operation environments.

RB14eU installs directly into a standard PCIe slot and includes both low-profile and standard brackets, ensuring compatibility with slim and full ATX tower cases. SMA connector mounting holes and cable exit options simplify external antenna installation and cable management in rack or server deployments. Native support for MikroTik R11e interfaces ensures seamless integration within the RouterBOARD ecosystem.

Recommended for integrators building multi-WAN gateways on x86 platforms, for mobile connection aggregation systems at locations without fiber access, and for wireless connectivity testing labs. Also suitable for businesses looking to repurpose existing PC hardware as an LTE router or gateway without investing in dedicated appliances. This product is discontinued.
