Description: This kit allows controlling the speed of a DC motor in both the forward and reverse direction. The range of control is from fully OFF to fully ON in both directions. Normally, switches are used to change the direction of rotation of a DC motor. Change the polarity of the applied voltage and the motor spins the other way! However this has the disadvantage that a DPDT switch has to be added to change the polarity of the applied voltage. Now you have two things to control the motor – a direction switch as well as the speed control. Also, it is not a good idea to suddenly reverse the voltage on a DC motor while it is spinning. It can cause a current surge that can burn out the speed controller. Not to mention any mechanical stress it can cause as well. PCB size: 93mm x 42mm (3.625 x 1.625 inch)
