The MikroTik RBM33G is a full-featured RouterBOARD device that is ideal for use in your own enclosure or for creating a custom solution. It uses the same PCB form factor and mounting holes as its predecessors (RB433/RB953 series).
The RBM33G is equipped with a dual-core processor running at 880 MHz, 256 MB of DDR3 RAM, and three Gigabit network ports. It is specially designed for devices that require two 3G/LTE modems. Depending on the needs, you can use both miniPCIe slots to connect two miniPCIe 3G/LTE modems or connect only one such modem and one USB 3G/LTE using the second slot for connecting an 802.11 wireless card.
The card also features a USB 2.0/3.0 port that can be used to connect a 3G/LTE modem or external hard disk drive, and an RS232 serial port for console access. For memory expansion, microSD and PCIe M.2 slots are provided.
Power can be supplied to the device via the DC power connector or via the network port via PoE.
