The RBM33G, part of the renowned RouterBOARD series, serves as a versatile solution for those needing a high-performance OEM board.

Furnished with a two-core CPU operating at 880 MHz and accompanied by 256 MB of DDR3 RAM, it guarantees brisk performance.

The device possesses three gigabit ethernet ports, specifically designed for systems requiring dual 3G/LTE modems.

Users have the flexibility of integrating two miniPCIe 3G/LTE modems for varied mobile connections or employing one miniPCIe and one USB 3G/LTE modem, with an optional miniPCIe slot left for an 802.11 wireless card.

The inclusion of a USB 2.0/3.0 port means it's adaptable for either a 3G/LTE modem or an external hard drive. Additional features encompass microSD, PCIe M.2 slots, and a RS232 serial port.

With options for PoE or DC jack power sources, it's the ultimate solution for diverse networking needs.
