Compact, Customizable Design

The RBM33G is built for flexibility, designed to fit seamlessly into custom enclosures or bespoke networking solutions. It maintains the same PCB form factor and mounting holes as its predecessors (RB433 and RB953 series).

High-Performance Hardware

  • CPU: Two-core processor running at 880 MHz.
  • Memory: 256 MB DDR3 RAM ensures smooth operation for complex tasks.
  • Storage Expansion: Includes microSD and PCIe M.2 slots for additional storage.

Multiple Connectivity Options

  • 3x Gigabit Ethernet ports for high-speed wired connections.
  • 2x miniPCIe slots support dual 3G/LTE modems or a combination of LTE and wireless cards for versatile setups.
  • USB 2.0/3.0 port for external devices like a 3G/LTE modem or external hard drive (refer to the product’s Quick Guide for specific configurations).
  • RS232 serial port for console access.

Flexible Powering Options

  • PoE support via a Gigabit Ethernet connector.
  • DC jack for alternative power input.

Use Cases

  1. Mobile Connectivity Solutions

    • Connect two 3G/LTE modems for redundancy or increased throughput.
    • Use a miniPCIe LTE modem and a USB LTE modem for additional flexibility.

  2. Custom Networking Solutions

    • Add an 802.11 wireless card to create a wireless networking solution.
    • Utilize the M.2 and USB ports for storage-heavy applications.

  3. Industrial Applications
