A general-purpose, low-voltage power supply board was developed, designed for microcontroller-based control. The board accepts a 12-24 V input for a 0-8 V output, or 16-24 V input for a 0-12 V output, with a current range up to 5 A. It supports both constant voltage (CV) and constant current (CC) modes, making it suitable for various lab and automation applications.
