The RBM33G is a fully featured RouterBOARD device perfect for using in your enclosure or building a custom solution. It uses
the same PCB form factor and corresponding mounting holes as it’s predecessors (RB433 and RB953 series).
The RBM33G features a new two core CPU running at 880 MHz and 256 MB of DDR3 RAM and three-gigabit ethernet ports. It is specially designed for setups that require two 3G/LTE modems. You can use, e.g.:
• Two mini PCIe 3G/LTE modems for multiple mobile connections (two SIM slots provided)
• One mini-PCIe and One USB 3G/LTE modem leaving another mini PCIe slot for 802.11 wireless cards (consult product Quick Guide for details)
The included USB 2.0/3.0 port can be used either for 3G/LTE modem or an external hard drive (consult product Quick Guide for details). For expanding storage, microSD and a PCIe M.2 slots are provided.
The RBM33G comes fitted with an RS232 serial port for console access. PoE can power the device through its gigabit ethernet connector or the DC power jack.
