I'm a newbie to motor driver. Which one is better if I want to drive 4 units DC motors (1A) with Arduino Uno? Stalk 2 units dual channel 10A DC Motor Driver (MDD10A) or just use 4 channel 2A DC motor Driver (FD14A)? As I understand both are different in price only (RM26), anything should I concern in both power supply? Last but not least, why are some projects using rotary encoder kit or encoder for Polulu wheel since the projects have been using motor driver to control DC motors?

Since you are using Arduino and your motor does not exceed 2A, why don't you consider the 2A motor shield?

Hi Ober,

Thanks for your reply. I need to use a few servo motors in my project too. That's why I didn't choose this shield.
Is dual channel 10A DC motor driver (MDD10A) better than 4 channel DC motor driver since I need to control 4 DC motors (1A each)? Just make sure their power inputs are in parallel with battery. Can I use programming code from http://tutorial.cytron.com.my/2012/07/16/interfacing-fd04a-and-skps-with-arduino in order to program my Arduino Uno with MDD10A?

If the motors are within 1A, I will go for FD04A because it can control up to 4 motors with 1 board, while you need 2 of MDD10A to control 4 motors.

You can try to use the sample code from the tutorial, minor modification might be necessary depending on the pins you use.
