In this video, I show you the revised version of my ATmega32u4 microcontroller board. I decided to revise this board because in the future I want to start selling it, so I thought it would be a good idea to make a few and test if it works well. I also explain in the video how to upload a bootloader to a bare chip by using another Arduino as a programmer.

Get my board from my shop:
