Wii U Teardown

It’s been a long time, but after six years Nintendo has released a brand new revision of the Wii console: the Wii U. With all of its shiny new features and redesigned internals, we needed to get our hands dirty with an in-depth teardown of both the console and its innovative new GamePad controller.

Anxious to get a look at the new hardware, we dove into the console first. No big surprises here, as it’s assembled in typical Nintendo fashion with an abundance of hidden Tri-wing screws—no match for our teardown experts, but a pain for modders and repairers.

The Nintendo Wii U console opened up for the teardown

The GamePad controller’s imposing size is a result of the large screen and buttons, with plenty of room for the internal circuitry and even room for a much larger battery in the user-accessible compartment.

Aside from the use of Tri-wing screws on both the console and the GamePad controller, the two devices impressed us with their repairability and modularity. Designers opted for screws over adhesive or clips, most components can be replaced independently of their respective motherboards, and the battery is easy to get to and replace. In light of this, the Wii U scored an admirable 8 out of 10 on our repairability score.


* The optical drive and heat sink dominate the majority of the console’s internal Wii-al estate, and are considerably beefier than those found in the Nintendo Wii.

* At 424.2 grams, the Wii U’s optical drive accounts for nearly one third of the console’s 1.5 kg.

* We suspect that the large optical drive may be a by-product of the larger motherboard underneath. A case expansive enough to accommodate the motherboard leaves some extra room for a bigger optical drive. Possible benefits to using a clunkier disc-reader could be reduced cost, quieter operation, or improved longevity over a slimmer drive.

* Examining the underside of the motherboard, we found three separate wireless modules:

  • Broadcom BCM43237KMLG Wireless LAN module
  • Broadcom BCM43362KUB6 802.11n Wireless Module
  • Broadcom BCM20702 Bluetooth 3.0 module

* Notable ICs on the Wii U’s motherboard:

  • IBM Power®-based multi-core processor
  • AMD Radeon™-based High Definition GPU
  • Panasonic MN864718 HDMI Controller
  • Samsung KLM8G2FE3B eMMC 8 GB NAND Flash/Memory Controller
  • Micron 2LEI2 D9PXV(MT41K256M16HA-125) 4 Gb DDR3L SDRAM (4 x 4 Gb for a total of 16 Gb or 2 GB RAM)
  • DRH-WUP 811309G31
  • Fairchild DC4AY
  • SMC 1224EE402
  • Samsung K9K8G08U1D 4 Gb (512 MB) NAND Flash

* Good news for those looking to extend their playtime on the GamePad controller—there’s plenty of room in the battery compartment for an upgraded pack.

* The larger controller on the Wii U is a design choice, comfortably accommodating the screen, buttons, and circuitry with room to spare.

* Notable ICs on the Wii U’s GamePad motherboard:

  • STMicroelectronics UIC-WUP MCE GH226
  • STMicroelectronics MSA3D 01F
  • Texas Instruments TSC 2046I Low Voltage I/O Touch Screen Controller
  • InvenSense ITG-3280 Gyroscope
  • Micron 25Q256A 256 Mb Serial Flash
  • DRC-WUP 811309J31 1217LU603
  • Texas Instruments AIC3012 Audio Converter
  • Texas Instruments 1010007

* Separate button groups are good news for the button mashers among us, as each unit will be relatively quick and inexpensive to replace.
