LEGO Power Functions

LEGO Power Functions is a LEGO Technic based system of motors, lights and battery boxes. Motors and lights can be controlled directly through battery boxes or via remote control – the PF system includes a two channel Infra Red receiver and two types of handheld IR remote controllers. All components can be wired together by cables with special brick-shaped electrical connectors.

Let your models come alive
The Power Functions motors and lights enable you to move your LEGO bricks and get even more creative with your LEGO Technic models and trains. Move trains, cars, cranes and other creations.

Why LEGO Technic fans love BuWizz?



The unique feature of the BuWizz is as "Fast" mode, which provides a voltage that is higher than any LEGO-battery-based solution. It makes a noticeable difference in motor's performance.

The interface is simple and easy to understand and to connect. The default profiles are easy to use and the Buwizz responds very good to action on the phone. Plus a fast mode for the motor which enable 11V on it (no damage for the motor).

Therefore, I really encourage you to buy one, this is way better than sbrick. Despite the price, you have the equivalent of a working sbrick with a lipo battery which can be charger by a simple usb type B. So not too much money comparing to lego PFS solutions.

In principle this means Anto’s Citroen could drift, if only LEGO motors had a bit more power…

With the addition of a third-party BuWizz bluetooth battery brick however, they do. A lot more. The BuWizz system delivers up to eight times more power than normal to the LEGO motors, and that is easily enough to spin the rear wheels on a not just a hardwood floor, but pretty much anything.

The BuWizz is smaller and lighter than the Battery Box and delivers more power for longer. Perhaps the best feature is that the BuWizz has a high-power mode that delivers twice the power to the motors, enabling the motors to handle high loads from large builds or driving outdoors. Finally, you can drive your Lego vehicles on the grass or up slight inclines without having to worry if the motors can take it.
