If you send a PWM signal, you can control the speed of the motor.If you send a LOW signal to the enable 1 pin, motor A turns off.It uses the popular L298 motor driver IC and has the onboard 5V regulator which it can supply to an external circuit. If you send a HIGH signal to the enable 1 pin, motor A is ready to be controlled and at the maximum speed. This L298 Based Motor Driver Module is a high power motor driver perfect for driving DC Motors and Stepper Motors.… If the motor supply voltage is up to 12V we can enable the 5V regulator and the 5V pin can be used as output, for example for powering our Arduino board. 5V is used to operate the L293D chip, while 6-46V is used to drive the motors. The L298N is a dual H-Bridge motor driver which allows speed and direction control of two DC motors at the same time. The L298N IC is used for driving 2 DC motors. L298N Module can control up to 4 DC motors, or 2 DC motors with directional and speed control. This module consists of an L298 motor driver IC and a 78M05 5V regulator. Time to trace through this circuit and see if I can find them.This L298N Motor Driver Module is a high-power motor driver module for driving DC and Stepper Motors. Looking over the list of expected components, I am left with two missing: there are no candidates for current sense resistors. Finally the +12V label is mysterious, since everything I see with a voltage limit can go up to +35V and I see no reason to constrain it to +12V. Dual H Bridge DC Stepper Motor Drive Controller Board Module for Arduino DIY. There is a jumper nearby to disconnect something, possibly the 78M05? A small surface mount LED and accompanying current limiting resistor probably indicate power on one of the power rails. Buy L298N Motor Drive Board Module at cheap price online, with Youtube. The L298N motor drive is also capable of controlling stepper motors.

Mounted on an easy-to-use module, the L298N follows an H-bridge configuration for easily changing the direction of a DC motor.

But it is also possible it is a +5V input to bypass the 78M05. The L298N is a motor driver IC by ST Microelectronics. This module will allow you to easily and independently. GND is obvious enough, and given the presence of 78M05, my first guess is that the +5V terminal gives the option of tapping its output to drive our microcontroller. This dual bidirectional motor driver is based on the very popular L298 Dual H-Bridge Motor Driver IC. The third screw terminal block has three posts labeled +5V, GND, and +12V. If an application wants control over enabled state, we can remove jumpers and connect the enable lines for PWM speed control. My hypothesis is that they are tied to +5V to stay in the enabled state by default, allowing motor direction control going full speed forward, full speed reverse, and brake stop. Also straight from the data sheet are control signals IN1, IN2, IN3, and IN4. They are labeled OUT1 and OUT2 on one side and OUT3 and OUT4 on the other, designations straight from the L298N data sheet. Two blue screw terminal blocks on either side are motor output connections. L298 datasheet required a capacitor between motor voltage supply and ground, and another capacitor between logic voltage supply and ground, so that fits. The numbers indicate 220uF at up to 35V, matching the maximum limit of 78M05. Two cylindrical assemblies are likely electrolytic capacitors. Input voltage can be up to 35V, but must be at least 7V. Its datasheet describes it as a voltage regulator delivering 5V at nominal 500mA. A search for “M7 Diode” indicates they are 1N4007 diodes.Ī single rectangular package is etched with ST logo and designation 78M05. 10PCS DC Motor Drive Module L298N PWM Speed Dual H Bridge Stepper Motor Drives Board For Arduino Smart Car Diy Kit L298. Since the datasheet said an array of four diodes each are required for A and B sides, seeing eight of something on the board makes them candidates for those diodes.

Flanking it, four on each side, are small modules labelled “M7”. The main attraction with the big heat sink is the L298 itself, specifically the L298N variant. This is why after buying a batch of generic L298N motor driver modules, I decided to sit down and understand what I have on hand instead of just downloading someone else’s documentation. The internet is a great resource, but sometimes I want the experience of doing something on my own.
