ZnDiy-BRY Z-323 Buck-Boost Voltage Converter Module w/ Voltmeter Display - Green (5~25V)
Introduction: This module is a step-up and step-down converter and has voltage display. The performance is better than LM2596 and LM2577. Features: Input and output voltage can display alternately; The starting state can be set freely. This module has the function of controlling the start-up and shutdown by the button. So it can control the state of output easily; This module has the big power MOS to protect the circuit in case of connecting reversely. This can improve the efficiency and reliability.
