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.

= Key Features =
+High Torque Gearbox - The 1:48 gear ratio allows the motor to move a small robot car effectively [citation:2][citation:9].
+Simple TwoWire Connection Red wire (positive) and black wire (negative) for easy wiring [citation:9].
+BreadboardFriendly Often comes with pre-crimped 0.1" (2.54mm) male headers on the wires, allowing direct connection to breadboards or screw terminals [citation:2][citation:9][citation:12].
+Plastic Gearbox Features a lightweight plastic housing with plastic gears for costeffectiveness [citation:2][citation:5][citation:9].
