This board allows you to connect a Wii Nunchuck game controller to any development board with a UEXT connector. The Nunchuck will communicate with your board's microcontroller via I2C. This creates a simple way to add a comfortable user interface to your project. Wii Nunchuck controllers feature an analog joystick, two buttons, and a 3-axis accelerometer (LIS3L02AL).
UEXT Connector The MOD-WII-UEXT module can connected to the UEXT ports of dozens of microcontroller systems and development boards. Click on the architectures below for lists of compatible boards:
Nunchuck Controller Not Included If you don't already have a Nunchuck controller, you can purchase this UEXT adapter board bundled with a Nunchuck. We do not sell the Nunchuck controllers separately, and they are sold at very high markup (typically about $17 over their wholesale cost), so you might want to get the bundle even if you do already have a Nunchuck, just to have a spare available.
MOD-WII Demo Code The following examples are intended to be run on DuinoMite boards:
