DROK L298N Motor Drive Controller Board DC Dual H-Bridge Robot Stepper Motor Control and Drives Module for Arduino Smart Car Power UNO MEGA R3 Mega2560 Duemilanove Product Features Product Description Parameter: Chip: L298N Logic voltage: 5V Logic current 0mA-36mA Storage Temperature: -20 ℃ to ℃ to +135 Operating mode: H-bridge driver (dual) Drive voltage: 5V-35V Drive current: 2A (MAX single bridge) Maximum power: 25W Dimensions: 43x43x27mm Product features: 1.L298N as main driver chip makes strong driving ability/small heating/strong anti-interference 2.Use large-capacity filter capacitors and diode with freewheeling protection function, increasing reliability 3. The big problem is that Drok say their driver is 7A, but L298N current limit is only 4A.Item: 272585324126 DROK L298N Motor Drive Controller Board DC Dual H-Bridge Robot Stepper Motor Con. You might like to check out the following precautions paragraph. I read the Drok user guide and found that you need to be very careful when using this driver. Setup - Logic power first, then motor power.Ĭlose down - Motor power first, then Logic power. Otherwise motor might go crazy and burn out. It is important to follow the power switching on/off sequence. Important L298N/TB6612FNG Power Set up/Close down procedure Why isn’t my Raspberry Pi motor spinning?

Manual jumper wire signal testing by hand before writing any programĪnd I always recommend anxious newbies to go slow, and do jumper signal hardware and wiring checking before writing any software program. For example, your L298N have optocoupler which might invert the input signals. Or your hardware are compatible to L293D, but not L298N. L293D and L298N Hardware Incompatibilities # $ hostnamectl = raspberrypi Raspbian GNU/Linux 9 (stretch) Linux 4.14.34-v7+ arm In this case I can also try PWM and compare with yours. If you can run this program, but not the more complicated PWM version, then it is software problem, such as your enable pin cannot do PWM. If you cannot run this program, then it is hardware problem. I ran the simplified program without any problem. I removed all the comments and print statements. L298N H-bridge Motor Controller, DROK L298N Motor Driver Board DC Dual H Bridge Robot Stepper Motor Regulator and Drives Module for Arduino Smart Car Power UNO MEGA R3 Mega2560 Duemilanove : Amazon. I guess this is the same as PWM with duty cycle 100% To make it simple, I just set enable pin high. To debug your code, I made it as simple as possible, but not simpler. Changed it to the correct one (5th up) but still no motor turning. GPIO.output(MotorPin1, GPIO.LOW) # counter-clockwise Pwm.ChangeDut圜ycle(20) #decreasing dutycycle to 20
GPIO.output(MotorEnable, GPIO.HIGH) # motor driver enable GPIO.output(MotorPin1, GPIO.HIGH) # clockwise Pwm.start(50) #starting pwm with 50% duty cycle Pwm = GPIO.PWM(MotorEnable, 1) # configuring Enable pin (MotorEnable) for PWM) GPIO.output(MotorEnable, GPIO.LOW) # motor stop

Looking for thoughts on how to get the motor working on the L298 H-bridge.
#Drok l298n motor driver controller code#
I tested the code on an L293D chip which turns the motor and tested both L298 H-bridges with no success. Below is my code to test if the motor works - but it doesn't turn. I've connected it up to my Raspberry Pi 3 with BCM 12 as my PWM and 16 and 19 as my IN1 and IN2. I bought two DROK L298 H-Bridges to control my DC motor (one for backup).
