It clearly labels six motor output ports (A, B, C, D, E, F) and a charging port. The unit has a battery capacity of 600mA and provides 7.4V output.
- Motor Output Ports (A-F): Connect up to six individual motors.
- Charging Port: Used to recharge the internal battery.
- Power Indicator: Shows the operational status and battery level.
3. USB Charging Cable
A standard USB cable is included for recharging the controller's internal battery.
Setup
1. Remote Control Battery Installation
- Locate the battery compartment on the back of the remote control.
- Open the compartment cover.
- Insert 3 AAA 1.5V batteries, ensuring correct polarity (+/-). Batteries are not included.
- Close the battery compartment cover securely.
2. Charging the Power Functions Controller
- Connect the provided USB charging cable to the charging port on the controller.
- Connect the other end of the USB cable to a standard USB power source (e.g., computer USB port, USB wall adapter).
- The power indicator light on the controller will show charging status. Allow sufficient time for a full charge before first use.
3. Connecting Motors
- Identify the motor output ports (A-F) on the controller.
- Connect your compatible motors to the desired output ports. Ensure a firm connection.
- Note which motor is connected to which port for accurate control with the remote or app.
Operating Instructions
1. Remote Control Operation
- Turn on the remote control by pressing its power button.
- Turn on the power functions controller.
- The remote control should automatically pair with the controller.
- Use the joysticks to control the speed and direction of motors connected to ports A, B, C, and D.
- Use the forward/reverse handover buttons to change the direction of motors connected to ports A, B, C, D, E, and F.
2. Mobile App Control and Programming
The kit supports control and programming via a mobile application. Refer to the application's specific instructions for detailed usage.

Image: Mobile App Control Interface. This image displays a smartphone screen showing two modes of the mobile application: a remote control mode with virtual joysticks and a programming mode with numbered slots for sequences. This app allows for both direct control and programmable functions for the connected motors.
- Download the compatible mobile application (e.g., 'INVENT R' as shown in product images) from your device's app store.
- Ensure Bluetooth is enabled on your mobile device.
- Open the app and follow the on-screen instructions to connect to the power functions controller.
- The app typically offers both a remote control mode for direct operation and a programming mode for creating custom sequences and behaviors for your motors.
Compatibility
This power functions kit is designed for broad compatibility with various building block models and systems available on the market. It can be integrated into existing construction projects to add motorized functions, remote control, and programmable actions. The modular design allows for customization and enhancement of different vehicle types and structures.
Maintenance
- Keep the components clean and free from dust and debris. Use a soft, dry cloth for cleaning.
- Store the kit in a dry place at room temperature when not in use.
- Regularly check battery levels and recharge the controller as needed.
- Ensure all connections are secure before each use.
Troubleshooting
- No Power: Ensure the remote control has fresh AAA batteries installed correctly. Verify the power functions controller is charged and turned on.
- Motors Not Responding: Check that motors are securely connected to the correct output ports on the controller. Ensure the remote control or app is properly paired with the controller.
- Intermittent Operation: Check for any obstructions in the motor's movement. Ensure the controller's battery is sufficiently charged. Verify that the remote control and controller are within operational range.
