ATmega32u4 minimum system

Overview

Lead out all the available pins of 32u4, try to compress the volume as much as possible, and use the type-c interface, which is more practical than pro micro. The basic components are all from the Xuan master file. In fact, there are a lot of materials left over from the original. In order to save some money, I originally wanted to Make a separate pad for VCC D+ D- GND. It is convenient for everyone to weld the Type-C interface with flying wires to adapt to the Type-C holes at various locations. I may not have time recently. I hope you can comment more on this project. It is best to correct the errors in the project and publish it to the platform. Our DIY works provide better convenience.
