How to use the L298N Dual H-Bridge Motor Driver
They can be 1N Schottky diodes. The two enable pins should be tied together.
Basic circuit configuration LN. Motor Driver Truth Tables Here are some handy tables to show the various modes of operation. In this series we will explore how to use the LN in a number of actual tested and functioning circuits.
ll289 Perhaps an updated version will include these internally. An onboard 5V regulator is provided that can be used to power other parts of your robot’s circuitry such as an Arduino microcontroller.
Do not enable the onboard 5V regulator if you plan to supply more than 16V to your motors. When these pins are HIGH, power is output to the motor. One of the annoying features of the unit is the lack of internal parasitic flywheel diodes to deal with voltage spikes. In the proceeding sections we will connect the LN to a micro-controller to operate a bi-polar stepper motor and explore using pulse-width-modulation PWM to control motor speed on a standard DC motor.
D1 – D8 are used for this purpose. The motors will come to an instant stop. This completes our introduction to the LN dual full bridge driver.
Leave the jumper connected when not using current sense. Internally mtor LN consists of four independent power amps with 5-volt digital inputs and four high current, high voltage power amplifiers capable of driving single DC motors, and both unipolar and bi-polar stepper motors.

Welcome visitor you can login or create an account. The four amplifiers are usually used in pairs forming an H-bridge to switch polarity for to control the direction of a single DC motor or as two pairs of H-bridges a bi-polar stepper motor.
Shown in figure 3 the power amps have connected in parallel for double the power at the cost of operating one bi-directional load such as a DC motor.
The current sense pins in general can be tied to ground, but one can insert low value resistor, whose voltage reading is proportional to current. Refer to the details below. As shown in the above illustrations I have redrawn the “multi-watt” package into a more understandable form.
How to use the LN Dual H-Bridge Motor Driver
To use the current sense feature, remove the jumpers and attach to the header pins. This included power connectors, diodes, LED indicators, and even a 5-volt regulator. Follow the steps below to configure the motor controller board to work as a typical robot motor driver for use motod two DC motors.
It is powerful enough to drive motors from V at up to 2A peak. Connect these pins to digital outputs on your robots microcontroller.

The same method is used to control Motor B: Otherwise you must input 5V regulated power at pin 5 so that the circuit can operate properly.

Note motpr “forward” and “backwards” refer to the direction of the motors themselves. Usage Follow the steps below to configure the motor controller board to work as a typical robot motor driver for use with two DC motors. The longer the PWM duty cycle is, the faster the motor will turn. Do not enable the onboard ,289 regulator if you are supplying more than 16V to motors on pin 3 or the regulator will burn out.
