The MOD-WII-UEXT can be used with a MOD-WII you purchased with ICSP
connector to switch to UEXT connector. The WII NUNCHUCK is a controller
for the Wii game console. It has a 3-axis accelerometer, a X-Y Joystick
and two buttons. All these features are available through I2C
communication, which makes it perfect
for connecting through UEXT connector
. As these controllers are
mass produced for the game industry, they are at an incredibly low cost for the features they offer.
This small adapter might be connected to MOD-WII so the data is conveniently led via I2C to an Olimex UEXT connector.
