MikroTik RouterBOARD RB433UAH — Professional Router for SMB & Outdoor Networks

The MikroTik RB433UAH is a RouterBOARD with three miniPCI slots and three Ethernet ports, designed as the central node for distributed networks, complex wireless deployments, and ISP infrastructures requiring maximum connectivity flexibility. It was widely used in WISP setups, mesh networks, and multi-radio installations where several frequency bands needed to run independently on a single platform.

The Atheros AR7161 processor at 680 MHz and 128 MB of RAM provided stable performance for advanced routing, packet filtering, and simultaneous traffic across multiple wireless interfaces. Three miniPCI slots allowed three radio modules to operate concurrently — the ideal configuration for sector-based networks, dedicated backhaul links, or frequency band separation in WISP deployments. The RouterOS Level 5 license unlocked the full feature set of the platform, including hotspot, VPN, traffic queuing, and dynamic routing protocols.

The microSD slot and two USB 2.0 ports extended storage capacity for Webproxy cache, system logs, and Metarouter virtual machines, while USB 3G modem support added a backup internet path or mobile connectivity option without additional hardware. Passive PoE input and an operating temperature range of -30°C to +60°C were suited for outdoor deployment inside dedicated enclosures.

Recommended for WISP operators and network integrators building multi-sector wireless infrastructures, for installations requiring separate backhaul and client access on distinct frequency bands, and for any project where the RouterOS Level 5 platform with three simultaneous radio interfaces was the primary design requirement.
