Motherboard Mikrotik L11UG-5HAXD Wi-Fi 5 802.11ac

The Mikrotik L11UG-5HaxD motherboard is a compact RouterBoard designed for building low-cost outdoor CPEs or access points. It is powered by a Qualcomm Maple ARM-based CPU with 256 MB RAM, a USB Type-A port for storage or peripherals, and a Gigabit Ethernet port with PoE-in support. The board includes a Wi‑Fi 5 (802.11ac) radio with MMCX connectors for external antenna options and a beeper output for alarms or custom signals.

Advantages

The board combines a modern ARM-based processor and Wi‑Fi 5 radio in a small form factor, offering Gigabit Ethernet and USB connectivity along with PoE-in for flexible power options. MMCX antenna connectors allow use of external omnidirectional or directional antennas to adapt range and coverage. The compatible aluminum cases used for earlier RB series boards provide a reusable enclosure option for outdoor installations.

Suitable for

• Low-cost outdoor CPE and customer premises equipment
• Outdoor or indoor access points with external antennas
• Small networking projects such as kiosks, vending machines, ticket stations and ATMs
• Custom router or wireless bridge builds

Key specifications

• Wi‑Fi standard: Wi‑Fi 5 (802.11ac)
• CPU: Qualcomm Maple, ARM architecture
• RAM: 256 MB
• Ethernet: Gigabit Ethernet with PoE-in support (18–28 V for PoE)
• USB: USB Type-A port
• Power: DC input 12–28 V, maximum power consumption up to 15 W
• Antenna connectors: MMCX for external antennas

How to use

Mount the L11UG-5HaxD inside a suitable enclosure and connect the Gigabit Ethernet port for data and PoE power, or provide DC power within the supported voltage range. Attach external antennas via the MMCX connectors according to desired coverage: omnidirectional antennas for broad coverage or directional antennas for long-range links. Use the USB Type-A port for additional storage or supported peripherals and configure the board through MikroTik RouterOS to set up AP, CPE or bridge modes. The beeper output can be configured for alarms or custom notifications.

Recommendations

For outdoor deployments, install the board in a weatherproof aluminum case and choose an antenna suited to the intended range. Ensure PoE voltage and DC input meet the specified ranges and verify thermal ventilation for continuous operation. Reuse compatible RB-series cases when available to simplify installation and reduce waste.
