The educational game puts players' typing skills to the test as they record details of more than 400 Pokemon using the peripheral.
Nintendo's Wireless Keyboard features a standard key layout and comes with a compact stand. The accessory will also be compatible with other Bluetooth-supported products, including the 3DS.
Nintendo will also release Pokemon Black 2 and White 2, the first direct sequels in the series, later this year.
The games will be accompanied by the release of companion apps Pokemon Dream Radar and Pokedex 3D Pro on 3DS.
Learn With Pokemon: Typing Adventure is released for DS and 3DS on September 21.
