Με Altecco06/04/2020bought for the Oscar liang fume extractor and work wonderful.
Με cjovelectro11/04/2019I 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.
