The MikroTik RBM33G is a fully featured OEM RouterBOARD that allows you to design your own enclosure or integrate into existing solutions. It maintains the same PCB form factor and mounting holes as the RB433 and RB953 series, providing a familiar platform for developers and system integrators. Specifically designed for setups requiring dual 3G/LTE modems, this device stands out with flexible connectivity options. Technically, it offers high performance with a dual-core MT7621A processor running at 880 MHz and 256 MB DDR3 RAM. Three Gigabit Ethernet ports provide fast and reliable wired network connectivity. Expansion options are rich: two miniPCI-e slots allow simultaneous installation of two 3G/LTE modems, or one modem and one wireless card for a hybrid solution. Additionally, a USB 3.0 port, M.2 slot, and microSD card slot add storage and peripheral flexibility, while an RS232 serial port is ready for traditional console access. The RBM33G is suitable for a wide range of use cases, from industrial applications to mobile backup solutions. For example, with LTE modems in both miniPCI-e slots, you can create a high-availability security system or remote monitoring point. Alternatively, using one miniPCI-e slot for a Wi-Fi card and the other for an LTE modem yields a compact unit offering both wireless access and internet backup. Passive cooling, a wide operating temperature range, and power options via DC jack or PoE make the device durable for harsh physical environments.
