## Summary description

The Mikrotik RBM33G is a wired router featuring Ethernet LAN data rates of 10/100/1000 Mbit/s. It is powered by a MediaTek MT7621A processor with a frequency of 880 MHz and includes USB 3.2 Gen 1 support. The router is available in Black, Green, and Grey colors and supports PoE power source, making it versatile for various networking needs.

## Long description

The RBM33G is a RouterBOARD module designed for integration into custom enclosures or bespoke networking solutions. It follows the same PCB form factor and mounting hole layout as earlier RouterBOARD models (RB433 and RB953 series) and provides three gigabit Ethernet ports, a dual-core 880 MHz CPU (MediaTek MT7621A), and 256 MB DDR3 RAM. The board includes connectivity options for multiple 3G/LTE modems, USB storage or modems, microSD and M.2 storage expansion, and a serial console port. Power can be supplied via PoE on the gigabit Ethernet connector or through the DC jack.
Advantages
The RBM33G supports two 3G/LTE modems using two miniPCIe slots with dual SIM capability or a combination of miniPCIe and USB modem, while preserving an additional miniPCIe slot for a wireless card if needed. It offers USB 2.0/3.0 compatibility for modems or external drives, onboard microSD and PCIe M.2 expansion options for storage, and an RS232 serial port for direct console access. The device maintains compatibility with the PCB size and mounting points of earlier RouterBOARD models to simplify replacement or custom builds.
Suitable for
Customized router enclosures and industrial enclosures
Deployments requiring dual 3G/LTE failover or aggregation
Integrations where USB modem or external storage is needed
Projects reusing RB433/RB953 form-factor mounts

How to use
Install the RBM33G into your enclosure using the standard RB433/RB953 mounting holes. Populate the miniPCIe slots with 3G/LTE modems as required, or install one miniPCIe modem and one USB modem to leave an extra miniPCIe slot for an 802.11 wireless card. Connect the device to your network via the gigabit Ethernet ports and attach power either through PoE on the Ethernet connector or the DC jack. Use the RS232 serial port for initial console configuration if needed. For storage, insert a microSD card or an M.2 drive and connect an external USB drive to the USB port when required.
Usage recommendations
For reliable cellular operation, consult the product Quick Guide to verify modem compatibility, SIM slot configuration and recommended antenna connections; ensure firmware is up to date and follow standard grounding and enclosure ventilation practices when deploying in custom housings.
