Feature
    - This module uses the LM2596 chip, with high efficiency (up to 92%) and small heat. It can bear up to 3A current if with heat sink, or bear less than 2.5A without heat sink.
 
    - With low ESR filter capacitors of Sanyo, this module can make ripple voltage as low as 30mV.
 
    - This module has high reliability due to advanced producing process and strict test.
 
    - Output voltage can be changed between 1.25V ~ 30V
