It's a shame there is no replacement --- it is hard to find anything like it, anywhere.</p>

Looks like at the moment it would be somewhat hard to replace if I should need to do that.</p>

I'm a bit surprised SFE made the decision to go with only two output voltages on the breakout since a truly variable output would cover a lot more situations.<br>
...and putting another regulator on the output of this regulator doesn't count if you ask me. If you have enough adapters, I suppose you could make anything into anything else, but that's really not an elegant solution.</p>

However, this breakout is configured for only the two choices mentioned above in the description. I'd prefer something with a more continuous level of adjustability.</p>

If you need lower, just feed a adj. voltage reg. with this and you should be good to go. Need higher, probably would want to look into something else.</p>

Additionally, the input connectors are wired like a plumber's nightmare, not neatly like the output connectors. Note that you could use the JST connector on the input and pull more than 1A on the output, provided the input supply was high enough.</p>
