On the other hand, an Arduino board is a specialized tool built upon a PCB, incorporating a microcontroller and other elements to facilitate programming and prototyping. It is essentially a PCB enhanced with the ability to interpret and execute programmed instructions, making it a popular choice for educational projects, DIY endeavors, and prototype development. While a PCB offers a static layout, an Arduino board brings dynamic functionality, allowing for interactive and programmable electronic setups.

How to integrate Arduino into PCB?

Integrating Arduino into a PCB is a process that involves a series of well-planned steps to ensure a successful setup. Initially, one needs to have a clear understanding of the project requirements and the functionalities needed.

Next, the appropriate Arduino microcontroller must be selected based on the project’s demands. Following this, the circuit schematic should be designed using software like Eagle or KiCad, where all the necessary components are laid out and connected logically.

Once the schematic is ready, it transitions to the PCB design phase. Here, the physical layout of the board is designed, keeping in mind the optimal placement of components to facilitate easy connections and minimize interference.

After finalizing the PCB design, it is time to prototype the board. This involves printing the PCB layout on a copper board and assembling the components manually to test the setup.

Post successful testing, the final step is the production phase where multiple PCBs are manufactured and Arduino microcontrollers are integrated into them, ready for deployment in the respective projects.
