Powerful OEM board with three Gigabit LAN ports and two mini PCIe expansion slots

The RBM33G is a fully equipped RouterBOARD device that is perfect for use in your own house or for building a unique solution. It uses the same printed circuit board format and mounting holes as its predecessors (RB433 and RB953 series).
The RBM33G features a new 880 MHz dual-core processor with 256 MB DDR3 RAM and a 3 gigabit ethernet port. It is specially designed for configurations that require two 3G/LTE modems. For example, you can use:
- Two mini PCIe 3G/LTE modems (two SIM expansion slots provided)
- One mini PCIe and one USB 3G/LTE modem, leaving an additional mini PCIe card slot for the 802.11 wireless card
The included USB 2.0/3.0 port can be used for a 3G/LTE modem or an external hard drive. Micro SD and a PCIe M.2 expansion slot are provided for expansion.
The RBM33G has an RS232 serial port for console access. The device is powered by PoE via the Gigabit Ethernet connector or via the DC power supply.
