15A Single DC Motor Driver (แท้จาก DFRobot)

This is an ultra small size DC motor driver for room limited projects, while the impressive IC - LM2575 could provide a powerful way to drive 36V@15A motors. Also its UVLO (Under Voltage Latch-Out) feature provides a safe guard for your system. Besides all, it is very considerate to own an 5V output for Arduino or any other devices, and its interface is ESD (electro-static discharge) protection.

Features:

• Voltage supply: DC 12 ~ 36 V
• Voltage supply limit: 6.5 ~ 40 V
• Control signal Level (Compatible 3.3V/5V)
  • High: DC 2.0 ~ 5.5 V
  • Low: DC0 ~ 0.8 V
• Maximum continuous operating current:
  • 12A (no heat sink)
  • 15A (with simple heat sink)
  • 20A (with Thick Heat Sink/ Cooling System)
• Peak current: 110 A
• Speed control: PWM
• Minimum valid Pulse Width: 200 ns
• Maximum Output Current @5V: 500 mA
• Working Temperature: -25 ~ 85 °C
• Mounting Hole: M3
• Dimension (Length * Width * Height): 55 * 55 * 20 (mm)/ 2.165 * 2.165 * 0.787 (in)
• Weight: 42g

Shipping List:

• 15A Single DC Motor Driver x1

Tutorial

Here you will learn how to use PWM signal to control the motor through this motor driver, do some wiring according to the Connection Diagram below, and then upload the sample code below to the Arduino card, here we use a UNO as the controller, you could see your motor run forward for 3 second and then run reversely for another 3 seconds and repeat this behavior then.

This tutorial will cover how to use PWM to control a motor using the shield.
