Ubiquiti USW-Flex-2.5G-5 UniFi Flex Mini 2.5G Switch

The Ubiquiti USW-Flex-2.5G-5, also known as the UniFi Flex Mini 2.5G, is a versatile, entry-level Layer 2 managed switch released in early 2025, designed for compact deployments in homes, small offices, or as an extension in larger UniFi networks, providing multi-gigabit speeds without the bulk of rackmount units. It features five 2.5 GbE RJ45 ports (four for devices, one dedicated PoE input for powering), supporting auto-negotiation down to 10/100 Mbps for broad compatibility, with a total non-blocking switching capacity of 25 Gbps (12.5 Gbps throughput). Measuring 117.1 x 90 x 21.2 mm and weighing approximately 200 g, its fanless, desktop-friendly design ensures silent operation and flexible placement via included feet or optional wall/din-rail mounts. Powered by a quad-core ARM Cortex-A53 processor and 1 GB DDR3 RAM, it supports advanced features like STP/RSTP for loop prevention, port isolation, VLANs, QoS, and IGMP snooping, all managed through the UniFi Network app with zero-touch provisioning and Bluetooth setup. It accepts PoE (802.3af/at) input on port 5 or a 5V/1A USB-C adapter (included), drawing under 5W for efficiency. Strengths include its portability and scalability for up to 30 UniFi devices, but it lacks PoE output and dedicated uplinks—perfect for boosting wired speeds in WiFi 7 setups without complexity.
