This module is an adjustable step-down module. The output voltage can be changed by adjusting the blue adjustable resistance on the module. The input and output voltage difference is 2V, and the minimum output voltage is 1.23V.
In - (input negative), IN + (input positive), OUT - (output negative), OUT + (output positive) must be correctly connected, otherwise it may lead to module damage. 

Technical Specification:

  • Module Properties: non-isolated constant current and voltage module
  • Rectification: non-synchronous rectification
  • Input voltage: 7V-35V
  • Output voltage: 1.25V-30V
  • Output current: adjustable maximum 3A
  • Conversion efficiency: 92% (the highest)
  • Switching frequency: 150KHz
  • Output ripple: 50mV (max) 20M bandwidth
  • Load Regulation: ± 0.5%
