More info

Detail about Power Module 

This module LM2596 chip using homemade quality, high efficiency (up to 92%), heat a small, can easily bring up 3A (short) over current, long working hours is recommended for use in less than 2.5A current, while adding heat piece (10W output above).
This module uses the original filter capacitors with low ESR, low ripple voltage can 30mV, fully capable and linear power This module uses machine placement, reflow soldering, and each module before shipment after two hours of aging test, to ensure high reliability.


  • Input voltage: 3.2-40V
  • Output Voltage: 1.5-35V (adjustable) ,input must least high 1.5V than output
  • Output current: rated current 2A, maximum 3A (need to add heat sink), if the output power greater than 15W, combined heat sink is proposed.
  • Conversion efficiency: Up to 92% (output voltage higher, the higher the efficiency) his is a high performance DC to DC step-down adjustable power supply module, switching regulator.
  • Minimum dropdown voltage:1.5V
