Mighty Tiny MikroTik Switch

Don't Let the Size Fool You

Two common traints of MikroTik devices is that they always get the job done and they tend to amaze. The same goes for one of MikroTik's smallest hardware products, the compact and sleek CRS305-1G-4S+IN, a Cloud Router Switch small in size and quite contrarily big on its performance.

Small but Significantly Strong

141 x 115 x 28 mm. That's how small the CRS305-1G-4S+IN is. Operating on an ARM 32-bit 800 MHz CPU and a RAM of 512 MB, this small and attractively designed Router Switch offers you both a notable performance concerning switching functions, as well as routing capabilities.

The CRS305 is equipped with a single copper Gigabit Ethernet port that is mainly intended for device management but can also be used for data transfer.

Below is a brief overview of the features of this tiny indoor switch:

  • Non-blocking throughput: 41 Gbps
  • Switching capacity: 82 Gbps
  • Forwarding rate: 61 Mpps
  • 2 DC jacks for redundancy
  • Maximum power consumption: 12 W (18 W w. attachments)
  • Supports PoE+ IEEE 802.3at/af and passive 12-57 V PoE-in

As you can see, with three powering options, that is, a pair of powering jacks on the back and PoE-in on this switch's Ethernet port, you can simply forget about any downtime for this device. Moreover, besides its beautiful metallic enclosure, the CRS305-1G-4S+IN is a fanless, silent hardware that works day in and day out without a fuss.

In addition, its dual-boot feature means you can easily switch between MikroTik's two leading operating systems, the SwitchOS (SwOS) with a more simplified interface that can fulfill all switching operations or the RouterOS that will allow you to use routing and other Layer 3 features in your CRS.

This tiny switch, given its silent performance, maximized uptime, and, of course, its 10G connectivity that is brought about for a very affordable price is perfect for home setups, such as home lab networks or gaming huddles, as well as small to medium businesses who are looking for a reliable switch without bearing any tangible financial burden.

Hardware Galore! Need a Hand?

MikroTik has accumulated an extensive and properly impressive inventory of connectivity hardware, with each item showing admirable performance.


However, when it comes to network design and implementation, it is crucial that you utilize each device in its most suitable and efficient place. Otherwise, it'll just be a great deal of time, money, and other resources down the drain.


With almost two decades of experience with MikroTik devices, we've been around long enough to know these products and their usages by heart. Let's have a talk and discuss your best options!
