RB912 board - new/old revision?

Hardware MikroTik hardware general
1

Hi,

I’ve bought a RB912UAG-2HPnD on Ebay. It came new and unused and in anti-static bag. But soon I realized that it differs somewhat. It does identify itself as 912UAG-2HPnD and has a valid license. I tried to find a picture of the same variant, but
was unable to.

Main differences what I noticed:

  • It has BGA type RAM
  • It has gold plated solder pads
  • It lacks the full bridge diodes (D1, D2), only single diodes.

Is this a new revision? prototype?

Either way it works fantastic. The reception is crazy even with lousy old D-Link antennas I had laying around. I have quite bad interference from other apartments, but I gained several Mbps more on average. The next step is to extend it with a 11ac radio.

We always update our devices without announcement or name changes, so yes, it is possible. There are currently four revisions to the RB912UAG-2HPnD

It would be good if they were registered somewhere differences between revisions …

there are no differences that would affect the user.

sometimes we change parts to other manufacturer, sometimes we optimise to make manufacturing easier.

Ok :slight_smile:

Maybe they don’t affect the user right now, but suppose one of the revisions develops a terrible failure rate–maybe low quality capacitors that start failing horribly after a couple years, to pick an arbitrary example. :confused: Naturally, you want to locate & replace these boards before they start causing unscheduled failures. Out of a hundred of these boards you have deployed, maybe a handful of them are the revision in question… but the only way to find them is to climb every tower and open every case for visual inspection.
