    RBM33G

    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 (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.

    1. All tests are done with Xena Networks specialized test equipment (XenaBay),and done according to RFC2544 (Xena2544)
    2. Max throughput is determined with 30+ second attempts with 0,1% packet loss tolerance in 64, 512, 1518 byte packet sizes
    3. Values in Italic indicate that max throughput was reached without maxing out CPU, but because board interface configuration was maxed out
    4. Test results show device maximum performance, and are reached using mentioned hardware and software configuration, different configurations most likely will result in lower results
