Routing a PCB is part engineering, part craft. Every trace carries the potential for interference or signal degradation. Follow these best practices for maximum stability.
Decoupling Capacitors
Never skip placement. Decoupling capacitors act as a buffer for your power supply, smoothing out voltage spikes that can crash your MCU.
Ground Planes
A solid ground plane is your best defense against EMI. Ensure your return paths are short and unimpeded to maintain signal integrity across the entire board.
