The LEGO PoweredUp system was introduced in 2017 as the successor of the PowerFunctions system. The system is centered around smart battery boxes known as hubs, featuring a BlueTooth connectivity, making it possible to connect them to apps on your mobile devices for full control of your LEGO models. Separate themes like City Trains, Technic, BOOST, Mindstorms and SPIKE all have their own type of hub and all were given an accompanying app to control official LEGO models.
