I just went through that due to a failing hard drive.? It was starting to drop sectors, but showed the problem as lockups when accessing various subsystems, such as serial ports.? Replaced the spinning hard drive with an SSD drive, reinstalled the Linux OS and all is well again.

Found these on Amazon. Descent price. Good to have handy in the parts box.

Had never heard of Drok, they have lots of stuff up on Amazon.
Does your Drok allow you to set the max current anywhere from 0 Amps to say 5 Amps?
Sorely needed.

Lots of cheap switchers out there now, but none of them seem to deal properly with current limiting.
Should be able to set both the regulated voltage and the max current.
If the load sucks too much current, the voltage drops until the current comes within the set limit.

Any of those switchers could do this for the price of an op-amp and a pot, maybe an extra $1.

A little more expensive model put out by droke even has a current limiting feature.
