MikroTik RouterBOARD L23UGSR-5HaxD2HaxD – Wi-Fi 6, 1x GbE RJ45, 1x SFP

The MikroTik L23UGSR-5HaxD2HaxD is a modular dual-band Wi‑Fi 6 board designed for building custom outdoor access points, CPEs and embedded network products. It combines a Qualcomm Maple ARM CPU, dual‑band Wi‑Fi 6 radio (2.4 GHz and 5 GHz), Gigabit Ethernet with PoE‑in, a 2.5 Gigabit SFP port, a USB port and a free miniPCIe slot for expansion. The design includes four MMCX antenna connectors, a NanoSIM slot for cellular modules and a beeper for alarms or notifications. The board supports long-range links depending on antenna choice and environmental conditions.

Advantages

This RouterBoard brings Wi‑Fi 6 performance to DIY and OEM projects, offering improved throughput, stability, roaming and power management compared with previous Wi‑Fi generations. Built‑in PoE‑in (18–28 V) and low maximum power consumption (25 W) simplify outdoor and embedded deployments. The modular hardware — USB, miniPCIe slot, NanoSIM and SFP — enables flexible customization such as LTE backup, LoRa gateway integration or fiber uplink. Four MMCX connectors allow selection of antennas for short‑range omnidirectional APs or long‑range point‑to‑point links.

Suitable for

• Custom outdoor access points and customer premises equipment (CPE)
• Small office, home lab and embedded OEM network products
• Long‑range wireless links and point‑to‑point bridges (antenna dependent)
• Deployments requiring PoE power and fiber uplink via SFP

How to use

Install the board in a compatible outdoor enclosure or custom device chassis and connect power via PoE‑in (18–28 V) on the Gigabit Ethernet port. Attach suitable antennas to the MMCX connectors according to the intended coverage or link distance. Use the miniPCIe slot to add modules (for example LTE or LoRa), insert a NanoSIM if using a cellular modem, and connect fiber through the 2.5 G SFP when required. Configure wireless, routing and security settings using MikroTik RouterOS or the provided software tools, and mount the finished assembly in its intended outdoor or indoor location.

Recommendations

For reliable long‑range links, choose high‑gain directional antennas and verify local regulations. Use PoE with a compatible injector or switch supplying 18–28 V. For outdoor deployments protect the board in a weatherproof enclosure and ensure proper grounding and surge protection.
