Grayed You can drive the motors with 5V to 35V. The module has two screw terminal blocks for the motors A and B, and another three-terminal block for the Ground pin, the VCC for motor and a 5V pin. The module has an onboard 5V regulator which is set with a jumper. This gives you three choices for powering the board and motors.1) The 5V pin can be used as an input, to power the board and run two 3 to 5V motors, or maybe even a 6V motor running slow. For example, you can take the 5V output from an Arduino to power the L298N. Turn off the 5V jumper in this case. Nothing will be connected to the left screw terminal.2) Between 6V and 12V - . If the motor supply voltage is 6V to 12V, enable the 5V regulator and the 5V pin becomes an output and can be used to power 5V circuits (such as an Arduino) while still supplying 4V to 10V to the motors (the L298N has a voltage drop of around 2V)3) Over 12V up to 35V -- WARNING! A supply voltage greater than 12V will cause damage to the onboard 5V regulator (resulting in smelly smoke and a dead Vreg), so you must set the jumper to turn off the regulator before using more than 12V. With the regulator off, you must supply 5V input to run the onboard logic.
