As of August 2018 the State of California has changed the requirements of the “Prop 65” law. We now must list on our website any possible chemicals the can cause cancer, birth defects or reproductive problem.
As an example:
ABS plastic contains styrene
PVC wire insulation can contain Di(2-ethylhexyl)phthalate (DEHP)
electrolytic capacitors can contain Ethylene glycol
Brass can contain Lead
flame retardant pc boards can contain Tetrabromobisphenol A (TBBPA)
Aluminum alloys can contain Chromium
To put it simply we are a small company and do not have the resources to test every single part, so we list every thing as hazardous. Please recycle all electronic parts responsibly and under no circumstance eat, drink or smoke these parts and wash your hands after touching!
These little SMPS are tiny and powerful. Im using mine to step down 12v to 5v, and yes the tiny trim pot is a little fiddly to adjust but be patient and steady your hand, it is possible. I dont know about the 3a rating, never pushed that hard, but they keep their cool running about 1a at 5v out.

Excelent instructional video.
Clear, concise, useful information. Covers most important points without wasted time or excess verbiage. Images are in focus and steady. Speech is clear and distinct,volume remains constant. ....Perfect.....
Real time saver
I build a lot of utility modules and these are great to drop in and be done! High efficiency is a real benefit over an 78xx linear plus I dont have to add the in and out caps; When a project requires 24V input and Im regulating down to 5V even 100mA is about 2W that a 7805 would dissipate. I keep a bag of these as well as the tiny boost converter that MPJA sells on hand at all times. The pot is tiny but all this takes is an appropriately sized screw driver and a light touch.

Blah once again not working
I can turn the adjusting pot 360° and get the same 4.04 volts, this is just with my multimeter possible with a load I might be able to adjust the output, so far very disappointed.

Very good down converter
I needed a 5 volt source to drive USB type drone battery chargers. I used this converter to build a 12 volt driven field charger that has four 5 volt channels allowing me to charge 5 drone batteries at once.
These micro converters work well. The only caveat is that you must turn the adjustment pot to max and back to min a few times and then set it to full clockwise. Connect your source and then adjust the pot slowly until you get the desired output voltage.
So far no problems with these units and they work great.

Not able to adjust voltage
I ordered 4 of these, it must take a special tool to move the adjustment so I am unable to adjust the voltage making them so much junk to me. This is the first thing from MPJA that I have had trouble with.
