Prior to designing this, my PCB design tool had been eagle but i decided it was time for me to learn a professional tool and i chose Altium designer as that tool. I researched online and saw that taking fedevel “Learn to design your own boards” was the way to go so I took the course and designed my own arduino board with the knowledge from the course. The board is of course based on the Arduino uno open source schematic which has the Atmega 328 microcontroller at it’s heart. The altium files can be found here.
