N20 Micro Gear Motor 6V
by Generic
SKU: PSA-CMP-N20-MOTOR
No reviews yetTypical India street price
₹80–₹220
Tiny metal-gear motor for compact robots and locks.
Interface: DC 2-wire; optional encoder
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
Same DC + gearbox idea as BO motors, much smaller.
A little theory
Stall current 0.5–1 A. Encoders (magnetic) on “N20 with encoder” variants. In the classroom, treat N20 Micro Gear Motor 6V as a beginner part using DC 2-wire; optional encoder. Typical India street price is about ₹80–₹220. 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
TB6612 or MOSFET driver; don’t drive from GPIO.
Classroom & project use
- Mini sumo
- Smart lock
- Pan mechanism
Buying in India
Precautions
- Share a common GND with the microcontroller
- Verify polarity and voltage before powering the circuit
