Wanted a speed controller for my Ultrasonic project. I needed to control the motor and have an indication of what input I was using so I could evaluate the best speed. This is perfect with the digital display of duty cycle. My only comment (not necessarily criticism) is that when I supply power to the unit it automatically switches on. I would prefer it not to come on till I push the "on" button. Though once switched off with the button it stays off till switched back on again. This means that when I power down I have to remember to have the duty cycle at 0 so the motor doesn't drive as soon as it is powered up. This is only a personal preference and hence does not stop me giving it 5 stars.

I've bought about half a dozen of these in the past, very useful little items easy to mount and wire, work perfectly.. I tend to try and keep a couple in stock for when I'm building interactive displays, also great as speed controller on miniature tools. Would recommend Would recommend
