10. Peripheral Line Suggestion
Wi-Fi module is already integrated into high-speed GPIO and Peripheral interface, which may be
generated the switch noise. If there is a high request for the power consumption and EMI characteristics,
it is suggested to connect a serial 10~100 ohm resistance, which can suppress overshoot when switching
power supply, and can smooth signal. At the same time, it also can, to a certain extent, prevent
electrostatic discharge (ESD).
