Buck converters and fusing


Chuck M
 

Finally found the link for the ones we got.  Used for both running 12V fans on our 3D printer, replacing the noisy 24 vdc OEM ones.  And for providing 5 vdc to run my RPi 3B from 12 vdc battery.  Worked well for us.


Printed case to hold them.


And fuse holder to protect the RPi in case of a problem.



Lots of other choices available depending on what your interests and pieces / parts happen to be.
