Component check (limesdr mini)

I have a limesdr mini board completly dead. No output from lsusb. And the led is orange.

Can anyone help me to see if there is some component missing or short circuit?


Hi @shao,

Was it working before?

Yes. It was normal before. I suppose there might be component missing now. Or maybe some place is short circuit?

I see no obvious damages. Would check if both power supplies are OK. Would check on C185 and C188 capacitors. Should be 2.5V and 1.4V respectively.

Thanks. I will check that.

Hi Zack,

I did the check.
C188 is 1.4V, which is right. But C185 is only 1.24V.

On windows, this board is recognized as unknown device.
