    I used these in many projects. Handy and cheap little step down modules. 12v to 5 volts works great. Haven't tested higher voltages yet. Only one thing: keep in mind to check for shortage! The common ground is almost touching the input and output positive pads (see photo). Overall, great and useful little modules.

    Looks good. I haven't tried it yet, though.

    Modules to lower the voltage at a very good price and of good quality. The product comes well protected for shipment.

    lo recomiendo para bajar el voltaje de alguna batería para que lo puedas utilizar con menor voltaje. es muy pequeño

    I received 5 units that were fixed at 5.1V. A fixed resistor was mounted in place of the potentiometer used to adjust the output voltage. So the description does not match the product as delivered. Beware if you need a variable output. No problem for me as I intended to use them for 5V anyway, and it's easy for me to swap out the resistor or install a potentiometer should I need a different voltage. I selected these for their low idle current, which was measured 200uA (0.2mA) at 12V.
