Description
Powerful OEM board with three Gigabit LAN and two miniPCIe slots
The RBM33G is a fully featured RouterBOARD device perfect for using in your own enclosure or building a custom solution. It uses the same PCB form factor and same 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 requires two 3G/LTE modems. You can use e.g.:
• Two miniPCIe 3G/LTE modems for multiple mobile connections (two SIM slots provided)
• One miniPCIe and One USB 3G/LTE modem leaving other miniPCIe slot for 802.11 wireless card (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 a RS232 serial port for console access. The device can be powered by PoE through it’s gigabit ethernet connector or through the DC power jack.
