As shown in the figure, for such a circuit, the voltage at the WAKE point is about 20V without a voltage regulator. Will the voltage at the WAKE point be 18V after adding a voltage regulator?
In this experiment, serial port software is used to send command words to GD32L233C-START through USART to control the working status of the onboard LED.
