Function introduction

Module principle: The LM7805 device provides a set of power supply solutions for low-power single-chip microcomputer products. When the lithium battery or adapter power supply is used, it can output a stable 5V voltage and the output current can reach 0.5-1A. It is convenient to connect with all kinds of control microcontroller chips and display instruments to realize constant voltage output power supply, and can be widely used in various occasions where power supply needs to be changed.
