Low Output - High-Power Motor Driver 18v15

I am using the High-Power Motor Driver 18v15 motor controller to drive a 12V brushed motor via Arduino Uno PWM.

I am getting only 50% of the expected output speed throughout the PWM range.



I am sorry you are having problems with your high-power motor driver. Could you tell me more about your setup? What are you using as a power supply? What motor are you running with the driver (what is its stall current and rated voltage)? How are you measuring the motor speed? Could you post pictures and a diagram of your setup? Could you also post the simplest version of your code that still demonstrates the problem?
