Regulador de voltaje ajustable LM317 Módulo de fuente de alimentación reductor LED metros
The module is ok. If you use it with a low current input, you can control a low range of voltage. I use it to control a 1 w power led . Certainly, the sensitivity is limited but is able to drive the LED between 2 and 3 volts with a 6 volt input about. It is the into of a microscope and I control the mirror rotation and outside light and service.
