This module works perfectly. He controls the Zumo crawler chassis from Pololu. The PWM is welcome to compensate for the difference in speed of small engines so that the robot goes straight.

Very reliable
This is ideal to make fancy robots using powerful DC motors. Non of the 3 I'm using has been broken so far and the alowed PWM frequency is high enough to avoid noise. One drawback is the need for individual closure of the half-bridges inside (at least for my project which is about controling a simple DC drive in 2 directions). You can however save one pin per full bridge if you use a hex-inverter to generate the input for the secondary half-bridge. All in all - very cheap, very good!

Compact Size, Well built
I am using this to drive 2 x Pololu gear motors using a MSP430G2553 and it works great. Positives: Pins functions are labelled right on PCB Small size Well built Reliable Does not overheat Negatives: Lots of control pins. Each motor requires IN1, IN2, PWM, and STBY to operate.

Great product
Easy to use and works very well !

Better that expected
These drivers work very well. I was concerned about heating as I am driving a 12V motor at 2A but these devices stay quite cool - cannot detect any temp rise but just touching them with my finger.
