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 w... Read more
Involvement:General (knows how to use it) - Ownership:more than 1 month Pros:Very small and easy to fit.
Clearly labeled connections.
Works as advertized. Cons:Could have been shipped with some power connectors installed which would make life easier.
Voltage adjuster needs many turns to start acting up for different input voltages.... Read more
Involvement:General (knows how to use it) - Ownership:1 week to 1 month Pros:It does what it;s supposed to be doing and it is cheap. Cons:I used it to feed a 24 channel servo driver with 5V. The original source was 18V 6A, and the average current consumption on the driver peaked at ~1.5A during the testing of some servos. The problem is that aft... Read more
Involvement:Expert (understands the inner workings) - Ownership:1 day to 1 week Pros:Good quality converter, high quality Pcb material with red coating and good solder quality. smal size PCB low energy loss. The default outputvoltage = 12V.
You can adjust the voltage by turning the small screw on the PCB. Cons:the divice cannot deliver more than... Read more
Involvement:Expert (understands the inner workings) - Ownership:more than 1 month Pros:This module was exactly what I was looking for.
In my rc planes I needed to power a little camera, so I used this device to step down the voltage. It is simple to use, easy to adjust voltage. Since I do not use it to draw a lot of current, in my case, the unit... Read more
Involvement:Expert (understands the inner workings) - Ownership:1 week to 1 month Pros:Cheap, small, enough powerful DC-DC convertor that is suitable for DIY projects. You can achieve up to 2A continuous current with additional heatsink. Cons:Without heatsink it becomes too hot at current near 1A; coil at 2A current is 10-15C hotter than other b... Read more
Involvement:Expert (understands the inner workings) - Ownership:more than 1 month Pros:Very small unit wich makes every voltage below the input possible, with high efficiency and a good current.
Produces almost no heat and is stable, within the specs of the manufacturer. Cons:A pot for regulate the currentlimiter would be nice.
In that case this... Read more
