5-36V to 3V3 DC-DC step-down module

Overview

This is my first time designing, so I hope you can give me more suggestions.

Mini DC-DC step-down module (MP4462DN) input: 5V-36V output: 3.3V

After welding, multimeter test, the output voltage fluctuates between 3.24V~3.26V.
All use 0603 resistors/capacitors to facilitate your own patching.
Same as on Taobao Mini DC-DC pins are compatible, but the withstand voltage can reach 36V. (Taobao search: DC-DC 3A mini step-down module car power supply 6V9V12V-30V to 3.3V/5V output)
There is no circuit or copper laying directly under the inductor to reduce interference .
