Mini MP1584EN DC-DC BUCK Adjustable Step Down Module Effect Higher Than LM2596
Step Down Power Module DC-DC 3A Adjustable Step Down LM2596 Ultra-Small Size
Ultra-Small Size Step Down Power Module DC-DC 3A Adjustable Step Down Module LM2596

Application:
DIY mobile power supply, monitoring power supply, children's car power supply, camera power supply, vehicle power supply, communication equipment power supply, all kinds of occasions (such as aircraft model) that have strict requirements on volume and weight.

Note:
This is buck converter. Only used to lower voltage, not to raise voltage, so the output voltage should be lower than the input voltage.
If the output voltage is always equal to the input voltage. Please first turn the potentiometer clockwise more than 10 laps.
Please make sure that this module is within its working range before using.
Do not use without load or light load (less than 10% of output power) or connect too much things on one module.

Package included:
10 X MP1584EN DC-DC Buck Converter
