The MikroTik RBM33G is an OEM RouterBOARD with three Gigabit Ethernet ports, two miniPCIe slots and two SIM slots, built for custom setups with two 3G/LTE modems.

It uses the same PCB form factor and mounting holes as the RB433 and RB953 series, and fits the CA433U indoor case. Modem options include two miniPCIe 3G/LTE cards, or one miniPCIe and one USB modem with the other miniPCIe slot used for a wireless card. Storage can be expanded with microSD or the M.2 PCIe slot.

Key features

  • 3 x 10/100/1000 Ethernet ports
  • 2 x miniPCIe slots, 2 x mini SIM slots, 1 x M.2 slot
  • USB 3.0 type A port and microSD slot
  • MT7621A dual-core CPU at 880 MHz, 256 MB RAM
  • DC jack or passive PoE-in, 11-28 V
  • RS232 serial console and GPIO header, RouterOS level 4
