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.
