BO Dual-Shaft DC Gear Motor (TT motor)
by Generic
SKU: PSA-CMP-BO-MOTOR
No reviews yetTypical India street price
₹40–₹90
Yellow plastic-gear motor used on almost every Indian 2WD kit.
Interface: DC (needs driver)
Always drive through an H-bridge (L298N/TB6612), never from a GPIO pin.
Connect motor terminals to driver OUT; driver IN/PWM to MCU.

Concept
A DC motor spins when current flows; gears trade speed for torque.
A little theory
Back-EMF, stall current, PWM speed. Never drive from MCU pins. In the classroom, treat BO Dual-Shaft DC Gear Motor (TT motor) as a beginner part using DC (needs driver). Typical India street price is about ₹40–₹90. Always verify voltage and pin labels on your exact module — silk screens vary across clones. Start with a datasheet or trusted learn guide, power the part correctly, share GND with the MCU, and test with a simple blink/read sketch before building the full project. Measure voltages with a multimeter when something fails, and keep actuator current off the MCU regulator.
How it works in a project
Connect through L298N/TB6612. PWM = speed, IN pins = direction.
