TT Robot Motor (DC Gearbox Motor)
= Affordable DC Gearbox Motor for Arduino Smart Cars and Robotics =
The TT motor is a low-cost DC gearbox motor widely used in DIY robotics and Arduino projects. Also known as a "BO" motor, it features an attached gearbox that reduces speed while increasing torque, making it ideal for driving the wheels of small robot cars.
LowCost and Widely Available A budget-friendly motor choice for educational and hobby robotics projects.
Integrated Gearbox - Provides increased torque for moving robot chassis.
The motor is typically rated for 3V to 6V DC operation .
It is commonly used with motor driver modules like the L298N or L9110S.
These motors have no built-in encoders or speed feedback .

= Troubleshooting =
Motor not running:
- Check 3-6V power supply is connected.
- Ensure the motor driver is receiving a valid control signal.
- Verify wiring connections are secure.
- The red wire is positive (+) and the black wire is negative (-) .
Motor lacks power:
- Ensure the battery/power source can deliver enough current under load.
- Check for any mechanical obstructions or debris in the gearbox.
