Motorola XOOM (Verizon) Teardown

Motorola XOOM: In the box

As of this writing, the Motorola XOOM is available in the U.S. for $599 (with a 2-yr contract from Verizon) or $799 (with no contract). It runs Google's Android 3.0 (Honeycomb) operating system. The first XOOMs are 3G models, but Verizon plans to offer an LTE 4G upgrade. Once we begin dissecting the device, you'll see how.

Motorola XOOM: SIM card and microSD card slots

The Motorola XOOM has a single opening for the device's microSD card and SIM card slots. Both slots are filled with dummy cards made of clear plastic. According to Motorola documentation, neither can currently be used. The SIM slot will be used once the device is upgraded to LTE 4G and the microSD slot will be activated with a future software update.

Motorola XOOM: Removing the external case screws

The first step in opening the Motorola XOOM is removing the two Torx T5 screws located along the bottom edge. Luckily Motorola didn't use any security screws--like the annoying pentalobe screws Apple is using on several devices.

Motorola XOOM: Volume up and down buttons ribbon cable

Even with its two screws removed, you can't lift the plastic cover away from the Motorola XOOM's internal frame just yet. A thin ribbon cable for the volume up and down buttons (right side) still connects the cover to the main PCB.

Motorola XOOM: Antenna wires disconnected

The Motorola XOOM's antenna wires are held to the main PCB with metal clips. You can easily pull the wires out of the clips and away from the circuit boad. The wires will remain soldered to a contact plate attached to touchscreen's bezel.

Motorola XOOM: Display assembly and internal frame

More than a dozen screws and adhesive hold the Motorola XOOM's front panel to the metal frame and display. As you can see the touchscreen's controller chips without removing it from the display assembly, I decided to leave it in place. I want to put this unit back together in complete working order.

Motorola XOOM: Main PCB - Front

Looking at the top of the Motorola XOOM's main PCB we can't see any of the chips. They're all hidden beneath metal shields, and unfortunately the shields are soldered to the PCB. As I want to reassemble with XOOM in working order, I'm not going to risk damaging the chips or their contacts by cutting the shields loose.

Luckly, our friends over at iFixit did go through the painstaking process of removing the shields. So, we know that hidden under the shields are an Nvidia Tegra T2 dual-core CPU, Broadcom AGPS, Broadcom Wi-Fi, Bluetooth 2.1, and FM Tuner, Qualcomm HSPA+ chip and Samsung DRAM module.

For a closer look at the chips, check out iFixit.

Motorola XOOM: Main PCB - Back

Just like the shields on the front of the main PCB, those on the back are soldered in place. Again, iFixit comes to the recue. Under these shields, there are chips from Qualcomm, Atmel, Toshiba, and ST Ericsson.

Motorola XOOM: Disassembled

Overall the Motorola XOOM was very easy to disassemble. It has standard Torx T6 and T5 screws. The XOOM also feels like a sturdy and well constructed tablet. And, it should be for $800. Unfortunately, it's unlikely that you'll be able to get spare parts for XOOM anytime soon.
