Pin Configuration

  • N20-3V-200 RPM Micro DC Motor Documentation
  • Pins Explanation and Connection Guide
  • The N20-3V-200 RPM Micro DC Motor is a small but powerful motor designed for use in various IoT applications. It has a compact design and is suitable for use in robotics, drones, and other small-scale projects. The motor has three pins, which are described below:
  • Pinout:
  • 1. GND (Ground Pin)
  • Function: Provides a ground connection for the motor.
  • Connection: Connect to the ground pin of the power source or the negative leg of the battery.
  • Important: Ensure a secure connection to prevent motor damage or malfunction.
  • 2. VCC (Power Pin)
  • Function: Supplies power to the motor.
  • Connection: Connect to the positive leg of the battery or the power source (e.g., 3V battery or voltage regulator).
  • Important: Use a suitable power source and ensure the voltage does not exceed 3V to prevent motor damage.
  • 3. Signal Pin
  • Function: Controls the motor's rotation direction and speed.
  • Connection: Connect to a microcontroller's (e.g., Arduino) digital output pin or a dedicated motor driver IC.
  • Important: The signal pin requires a PWM (Pulse-Width Modulation) signal to control the motor's speed and direction. A 0V signal will stop the motor, while a 3V signal will run the motor at maximum speed.
  • Connection Structure:
  • To connect the N20-3V-200 RPM Micro DC Motor, follow this structure:
  • Connect the GND pin to the ground pin of the power source or the negative leg of the battery.
  • Connect the VCC pin to the positive leg of the battery or the power source (e.g., 3V battery or voltage regulator).
  • Connect the Signal pin to a microcontroller's digital output pin or a dedicated motor driver IC.
