Introduction:

Any arduino based PCB usually needs extra circuits in order to fit directly in industrial projects. This project aims to design a custom industrial PCB that can be treated as the BluePill board—a popular and powerful microcontroller board—with extra circuits that allow direct connection of digital high current/voltage outputs (such as relays) and digital sensors with opto-isolators in order to work in high noise environments without need of extra driving circuits, in addition to multiple connectivity ports and analog inputs.
