A reader of Engadget has sent the website the above image of the user manual that came with their Fire TV Ethernet Adapter. Depicted in the updated manual is none other than the Fire TV Cube that was teased by Amazon yesterday through an information signup page. With a clear shot of the ports on the back, there is a lot we can assume about the upcoming Fire TV.
It appears that Amazon has decided to use the same Fire TV Ethernet Adapter for the Fire TV Cube that is currently used with the 3rd-gen Fire TV and 2nd-gen Fire TV Stick, instead of including a built-in ethernet port. This appears to be due to limited space for ports across the back of the device’s relatively small footprint.
For those of you thinking that there seems to be plenty of space to include an ethernet port above the depicted ports on the back of the device, remember that the ethernet port needs to be attached to the edge of the device’s circuit board. Judging by the placement of the ports on the back, the Fire TV Cube likely uses a circuit board positioned near the bottom of the device. This means that only ports on that plane would be possible without unconventional internal extension cables.
We have yet to see images of the sides of the Fire TV Cube, so there might be additional ports along the sides. That is what Roku does for some of their port-heavy models, but I personally doubt that will be the case for the Fire TV Cube. Due to the Fire TV Cube’s hands-free microphones and LD light bar, it will likely be best to place it somewhere visible, so aesthetics are more important for the Fire TV Cube than any Fire TV before it. For this reason, I can’t imagine having ports for cables sticking out of the side of the device.
The micro USB port on the back of the Fire TV Cube, used for the ethernet adapter, will likely be OTG capable, since that is the case with the 3rd-gen Fire TV and 2nd-gen Fire TV Stick. If it is an OTG port, it will probably accept USB peripherals and external USB storage using an OTG adapter or possibly even an OTG Hub. While this would not be as simple as a full-sized USB-A port, like on the 1st and 2nd-gen Fire TV, it should, at least, provide all the same functionality.
Since the Fire TV Cube in the image has a separate power adapter, the micro USB port likely cannot be used to power the device. This is the case for the Amazon Echo Spot, which also has both a micro USB port and a power port. The ethernet adapter manual also shows nothing plugged into the power port of the ethernet adapter, which is necessary for the 3rd-gen Fire TV and 2nd-gen Fire TV Stick.
Since the Fire TV Cube drawing shows the HDMI port, we can use that to approximate the device’s size. Assuming the ports on the drawing are to scale, the Fire TV Cube will be about 3 to 4 inches wide and a little shorter than it is wide. That would make its footprint larger than the pendant-shaped Fire TV 3 laid flat, but smaller than the Fire TV 1 and 2.
The last of the three ports is labeled “Infrared” according to the Engadget reader who submitted the image. It appears to be a round port that is about the same size as the power port. Since the Fire TV Cube is supposed to have IR capabilities to control home theater equipment, this port is probably how you connect its IR blaster.
Since the user manual lists the device as the “Amazon Fire TV Cube,” it’s probably safe to say that is the official name of the next flagship Fire TV. There is still a lot we don’t know about the device, but it seems like it won’t be too much longer before it’s released.
