The nice!nano is a Pro Micro drop-in replacement controller that provides wireless, BLE connectivity for your custom keyboards. Powered by the easy-to-use ZMK firmware, these controllers will allow you to ditch the wires and turn even split keyboards completely wireless.

Each nice!nano requires a 3.7v lithium rechargeable battery for wireless functionality. This battery sits comfortably under the controller and can be recharged by plugging the controller into a power source via its USB-C connector. You can pick some up here.

Please note: we cannot ship batteries anywhere outside the United States. For our international friends, you'll need to source your batteries elsewhere in order to complete your wireless builds. The 301230 lithium battery is a great choice.
