The primary aim of this board project was to familiarize us with the entire process of designing a functional PCB board using a practical and straightforward approach. To fulfill this objective, we selected an Astable multivibrator circuit that utilized a 555-timer.

The board was created to demonstrate the most efficient measurement methods for assessing the amount of switching noise in a PCB, and how layout decisions can impact it.
The board had 2 identical hex invertor circuits: Good layout designed with continuous return plane and decoupling capacitor close to IC. The bad layout was developed without the good design principles.

The purpose of designing and assembling a Golden Arduino board was to demonstrate that by following good design principles, one can reduce switching noise and crosstalk as compared to a commercial Arduino. The Golden Arduino had headers similar to a commercial one and could be bootloaded and programmed.
