Use LM317 Expansion Power Supply

Although I have a high-power power supply, it only provides a single channel of voltage. Since I require multiple voltage levels, I have decided to design an LDO supply module to regulate the voltage accordingly. I envision the supply module to be assembled in a manner similar to Lego blocks, allowing for easy expansion and modification.

Use Open-Source free software to designed this project.
