WiiU:Connector Pinouts

The Wii U uses the same pinouts as the predecessor, the Wii.

Wii U Multi A/V Connector Pinout
MODE pins: On PAL systems the default output is RGB + composite, on NTSC the default is S-video + composite. With pins 8 and 10 shorted, systems from both territories will switch to component video.

Pins 14, 15 and 16 are used by the Japanese D-Terminal cable. They are confirmed non-functional on PAL consoles.

Data Line 1: 0V = 525 lines (default) ; 2.2V = 750 lines ; 5V = 1125 lines

Data Line 2: 0V = 59.94i / 60i ; 5V = 59.94p / 60p

Data Line 3: 0V = 4:3 ; 2.2V = 4:3 letterbox ; 5V = 16:9

Wii U Other Connector Pinouts
The Wii U also has a Wii Sensor Bar connector for backwards compatibility with Wii games. The connector nominally outputs 12v, but the power supply circuitry makes it drop to around 7-7.5v under load.
