Enable (EN) is the 3.3V regulator’s enable pin. It’s pulled up, so connect to ground to disable the 3.3V regulator. This means that you can use this pin connected to a pushbutton to restart your ESP32. GPIO current drawn The absolute maximum current drawn per GPIO is source 40mA ...

将继电器的VCC输入使用3.3v,不要用5v,然后正常接GPIO,此时低电平0v,高电平3.3v,压差为3.3v,可以稳定工作。 (继电器的电源及信号输入都要来自ESP32) (水位传感器的也是如此,电源独立时,传感器信号不能正确传递) 参考: Esp32/Esp8266 稳定控制5v继电器
