If you supply more than 12V, you should remove the jumperĪt the bottom right you have four input pins and two enable terminals. Jumper removed: you need to provide 5V to the +5V terminal. Jumper: jumper in place – uses the motors power supply to power up the chip.Acts as a 5V output if jumper is in place +12V: The +12V terminal is where you should connect your power supply.For example, you can use a bench power supply to test this tutorial. In this tutorial will be using 4 AA 1.5V batteries that combined output approximately 6V, but you can use any other suitable power supply. It’s important to note that despite the +12V terminal name, with the setup we’ll use here (with the jumper in place) you can supply any voltage between 6V and 12V. Note: if you supply more than 12V, you need to remove the jumper and supply 5V to the +5V terminal.

However, if the jumper is in place, the chip is powered using the motor’s power supply and you don’t need to supply 5V through the +5V terminal.

The +5V terminal is used to power up the L298N chip. The +12V terminal block is used to power up the motors. OUT1 and OUT2 at the left and OUT3 and OUT4 at the right.Īt the bottom you have a three terminal block with +12V, GND, and +5V. The motor driver has a two terminal block in each side for each motor.
