  • Does the job. Cheap & customizable

    Involvement:General (knows how to use it) - Ownership:1 day to 1 week

    Pros:

    Pretty cheap. Wide voltage range. Useful for constructions when you need to get several voltage levels from battery of other lager level.

    Cons:

    No reverse input voltage protection. I 've destroyed one module in a few seconds just by wiring it incorrectly by mistake. Easy workaround is to solder protective diode in parallel.

    OtherThoughts:

    Got 3 of them, tested one for cellphone charging - 1A@5V, from battery set of 18V.

    Bottomline:

    Nice thing. I will perform the test with other voltages&currents I require in my constructions, and then probably buy more of them. Definetely worth the money spent.
