Today we’ll be taking a look at the Seagate BlackArmor NAS110 Network Attached Storage which has a single 3.5″ hard drive and 2x USB, it’s a pretty basic NAS. The date code is 2010/10th week.
Once the case comes off, you take the hard drive out and then slide out the PCB.
The top side of board looks like it has a lot going on but it’s more just all the part labels that make it seem that way.
We’ve got a 3V coin cell for a RTC, 2x chips most likely to be SMPS with a mosfet chip labelled 4468 BA012X / 4712 BV0226 as they are near the inductors, an APL1085 3.3V / adjustable 3A LDO and an APL5930 3A LDO. Something small that stood out to me was an SMD LED which emits its light horizontally instead of vertically.
