![]() ![]() Let’s take a closer look at the pinout of L298N module and explain how it works. The module can drive DC motors that have voltages between 5 and 35V, with a peak current up to 2A. We can add the wire connectors and heatsink. The L298N is a dual H-Bridge motor driver which allows speed and direction control of two DC motors at the same time. ![]() Pay attention to the insulation between the driver MOSFET and the heatsink or the installation plate. Control port distance: 2.54mm,Power port distance:3.96 mmĦ. Use shielded wires if the drivers board has more than 50 cm distance from the motor, otherwise it may lead to abnormal driving, affecting the normal use.ĥ. GND-Used for Driver board internal controlĤ. Connect 5V or no connect to allow operation, connect GND to forbid operation. Analog voltage linear speed regulation 0.1v -5V, The input resistance is 20K Ohm ,connect with GND when input PWM speed regulation, PWM frequency:1-20KHZ Duty cycle 0-100%ĮL -Enable port control. ![]() Connect “5V” high level or no connect is Forward direction, connect 0 V low level or connect to GND is reverse direction. and the driver has built-in 5V for speed control, DO NOT connect extra power supply( 5V ) into the driver for speed controlling, it will damage the driver.ĥV -Driver board internal output voltage, external potentiometer or switch for speed adjustment and reversing operation In this blog there are some posts show how to control brushless DC motors (sensored and sensorless BLDC motors) using Arduino (project links are below). It will damage the driver board permanently without insulation,and also apply Heat-Conducting Silicone Grease on the insulation for better cooling.ģ: As the BLDC motor factory may use different Hall sequence,if the motor start abnormal, can't start or the current getting to high, please adjust the sequence of the Hall, or the driver will be damaged.Ĥ:Please offer the right voltage to the driver, do not exceed the operating range. When installing the heat sink, please add insulation layer for 6pcs MOSFETs. ![]()
