Schematics for RB112

Hardware MikroTik hardware general

Hi,

I recently acquired a second hand RB112, but two caps were busted, one is the C71 and run in parallel with the C110, the two big ones close to the power source, and as they look equals on the net’s photos I guess they are both 105Cº 180µF 63V, and the other one seems to be a SMD ceramic cap numbered as C20 on the board next to the S1 button, so there is no other way to know it’s value unless I check the board’s schematics :frowning:…

So, does anyone know where and if I can get the schematics for the RB112?

Thanx.

It seems I’m out of luck :frowning: …

Can at least someone confirm if both capacitors are 105Cº 180µF 63V, C71 and C110 marked on attached photo with red circle?

RB112 seems to be like a relic :slight_smile: I have few RB512 on my desk, still working :slight_smile: Write if you have successfully reanimated RB112.

Those are C67 and C68 and their value is: 560μF 6.3V 105°C

While we are at it, does anyone know the value of C78?
It’s right behind the DC barrel connector and it’s an SMD one.

In year 2019 - this RB belongs to the trash

Besides suggesting putting it in a landfill, polluting the environment for no good reason, do you have anything on-topic to suggest?
Like for example, what is the value of C78?
