The WiiChuck Adapter is a small PCB that is designed to be inserted into

the connector of a Nintendo Wii Nunchuck to provide access to all 4

wires of the remote. The power, ground and two-wire interface of the

Nunchuck are all broken out to a 4-pin 0.1" pitch header. Compared with

standard WiiChuck, the DFRobot WiiChuck has extra 4 pins which allow you

connect it to two devices. The Wii Nunchuck is loaded with features -- a

2-axis joystick, two buttons and a 3 axis ?2g accelerometer -- and any

device capable of I2C can communicate with it! The WiiChuck allows you

to interface with the Nunchuck without making a mess and cutting the

wires. |Specification| Interface Type: I2C Voltage: +5 V|Specification|
