Layout Overview Power Connectors DigitalAnalog Headers

Layout Keep noise from the step-up and step-down converters away from analog components Get headers close to signals of interest but away from noisy power subsystem Use single point connection for power and ground to different areas Route a dedicated analog reference voltage line and filter with RC network
