[[File:Wii_Connector.jpg|200px|thumb|right|Pins on the Wii expansion controller cable]]The Wii Remote includes a 6-pin expansion port that allows external peripherals to be connected to it. Communications are bidirectional synchronous serial I2C, and the devices provide a virtual register block of length 0x100 that is mapped at 0xa40000 in the Wii Remote's address space (The 7-bit I2C address is 0x52). '''Communications are encrypted''', as detailed in [[Wiimote#Extension Controllers]]. Nintendo has currently released two extensions, the [[#Nunchuk|Nunchuk]] and the [[#Classic Controller|Classic Controller]]. In addition, Guitar Hero guitars and drums also act as extension controllers, although the Rock Band guitars and drums connect using their own system. The Balance board acts like a dummy Wiimote with its own type of extension controller. There are also many third party versions of classic controllers and nunchuks.
