Hi Bill - great teardown - no sign of an ETH PHY chip or ETH Transformer? I guess the PHY is integrated in the SMSC chip? And the ETH transformer inside the Ethernet Connector? Any idea who the RJ45 connector manufacturer is? If the TF is integrated in the connector then it's the smallest one I have seen so far - neat.
Thanks, Bill. Sorry for the nitpicking, but it's just that when I take something apart, I like to be able to put it together again and have it working as it should. Once you identified the battery cover catch/release button, I understood the gestalt of the thing. BTW, I made a slight error. The purple button on the bottom of the remote is not the reset switch, but the reset switch button. The reset switch is on the PC board at the tip of your thumb on picture 38.
Who cares what's on the inside as long as it preforms it's job. Mine is going on 2 years and has never missed a beat. Takes a beating and keeps on ticking. I've knocked mine off the shelf twice now while dusting and it still works like new. Roku Rocks!
Bill, I respectfully point out that the picture identified as the bottom of the remote PC board is in fact the top of said PC board. You also forgot to identify the purple dot attached to the bottom of the remote below the battery compartment on picture 39 as the reset switch. I also wonder what the purpose of the black thing out of the case on the same picture is, unless it is just a spacer. BTW, this is a very well built piece of equipment. Does it do its job, and how well? Or maybe you can point us to a review that puts the XS through its paces?
I am actually interested in seeing how the insides work. I love this machine and how it has help my family get rid of cable and save $60 a month. I would have cracked open my own Roku but I fear losing it :) Steven www.reddwarfmedia.com
Thanks for the note. Identifying the "top" and "bottom" of PCBs can be a tricky business. Often, PCBs are mounted upside down depending on the device's case and internal hardware layout. I often refer to the "top" of a PCB as the side with the processors or most of the chips--as I did here. As for the small "black thing out of the case" you mention, it is the catch/release button for the remote's battery cover.
