Pinout issues of ESP32

Tips from Expert for advance users of ESP32-WROOM-32UE-N4

• ADC2 is used by the WiFi driver. Avoid using ADC2 if your application demands WiFi Communication.
• Careful about the Strapping pin. Refer datasheet carefully, it may end up a not working PCB board or application.
• IO3 remains High during boot. Take precautions. Carefully consider the ESP32 Pinout.
• IO14 and IO15 outputs PWM signal at boot. Take precautions.
• IO34, 35, 36, 39 is input only pin. Do not use it for output operations.
