MP2315S-DC step-down module

Overview

The MP2315S module was used, operating on a buck converter principle. The specific selection was based on the official recommendation; however, you can also choose your own model using the formulas in the manual. Since I'm a beginner, I followed the official recommendation.
Key points for layout include separating signal and interference circuits, whether to ground the power inductor, and ensuring short and thick input and output circuits.
