Product Details :

Ultra-Compact High-Speed Powerhouse: Combines a miniature $6 ext{V}$ DC core with a low-ratio precision all-metal gearbox to deliver rapid rotation speeds at low operating voltages.
Durable All-Metal Gear Train: Heavy-duty steel and brass spur gears ensure superior wear resistance, low backlash, and long continuous operation without gear stripping.
Precision D-Shaped Output Shaft: Includes a standard $3 ext{mm}$ D-shaft for secure, slip-free mounting of wheels, pulleys, couplers, and mechanical levers.
Energy-Efficient Operation: Features low power consumption, making it ideal for battery-operated handheld devices, 1S/2S LiPo projects, wireless robotics, and IoT nodes.
Versatile Power Input: Optimized for nominal $6 ext{V DC}$ operation, but operates safely between $3 ext{V}$ and $6 ext{V DC}$ for variable speed control using low-voltage PWM motor drivers.

How to Use

Connect positive ( $+$ ) and negative ( $-$ ) supply wires to the solder tabs on the rear motor end-cap
Attach compatible wheels, gears, or couplers onto the $3 ext{mm}$ D-shaft
Connect motor leads to a low-voltage H-bridge motor driver (such as DRV8833, TB6612FNG, or L298N)
Apply up to $6 ext{V DC}$ power supply to the driver board
Control output speed using PWM signals and adjust rotation direction by toggling input pin polarities

SAFETY NOTICE: Do not mechanically lock or stall the output shaft for extended periods while powered, as high stall current can generate heat and damage internal gear teeth.
