Hello I need to power a L298n with 16v. But I need to power the Arduino or a ESP32 as well from the L298n. Because the power supply is higher than 12v I must switch the jumper and I cannot use the output of 5V. How can I do? In my project I cannot power the arduino or the esp32 with another source of power. Thank you very much.
Most people use a step down voltage regulator from the motor power supply to provide 5V to the 5V pin of the Arduino.

What jumper? An L298 doesn't have a jumper.
