DC Motor Driver, DROK L298 Dual H Bridge Motor Speed Controller DC 6.5V-27V 7A PWM Motor Regulator Board 12V 24V Electric Motor Control Module Industrial 160W with Optocoupler Isolation

This is an excellent book! For help getting started, see the following. In addition to a couple of 2-pole units, this unit meets all my application needs They are 3 amp DC motors and worth a lot more than they cost, and they stay cool so that no heat sinks are required I require frequent direction changes and large starting current spikes, but the board is worth the price. These connectors feature screw terminals and snap lock connectors that can be easily detached. The technical documentation looks great on glossy paper but would benefit from more I've listed a few tips and a test setup you can use with the Arduino Here are two examples 1) 2 This double H-will help you a lot There is the possibility of running two motors independently from each other over a bridge. 2) Each motor can be set to run forward, reverse, brake, or run at full speed forward or 3) Here are the categories of inputs (you provide them) for the board a) Main power (up to 15 amps) that is used for Make sure you pay attention to the specifications for voltages, current, peak current, fuses, etc. The board requires 5v power for its logic processing, e. g. b) Control logic for Motor A. c) Control logic for Motor B. d) 5v power for its logic processing, etc. Only a small amount of current is drawn. •

4) For the main power source, you must use a reliable power source. I am charging my batteries with a 10amp 5) You need to supply 5 volts to the board. The board has 5 volt (and ground) pins for each motor, but you only need to provide the ground on one set of the For motor #1, they are labeled IN1, IN2, CNC1 and ENA1. ) The third input is the ground. 2) Each of the two pins labeled IN1 and IN2 is fed from either of two GPIO(Arduino) pins with HIGH or LOW to control the motor mode, whether it be forward, reverse, or In the instructions, you can find the control logic table. This pin must be installed! 8) The pin labeled ENA1 is required! An Arduino PWM output must be used. You should NOT apply a steady voltage from a potentiometer or DAC. Here is a basic Arduino UNO test setup you can use H- should be connected to ground and 5V To test this, connect the bridge, connect the power, connect the motor(s), you only need motor A for this test, and plug in Ardunio Pin2 The following - Connect the bridge pin IN1 to the Ardunio pin 3. The following Pin ENA of the bridge is connected to pin 4 of the Ardunio board The following Input the following data into the test sketch * Create the following sketch The following code is in the setup() function The pinMode(3, OUTPUT) statement must be used. The following code will display the pinMode(4, The following code executes when forward
digitalWrite(4, AnalogWrite(3, 178) -- forward The PWM speed on pin 3 is 178/255, so (approximately) 70%. There is a maximum of 255 characters. delay (1500) This is the digitalWrite(2, HIGH) method revert digitalWrite(4) to the lowest possible level The reverse analog write is reverse
analogWrite(3) This pin is PWM, and it has 76/255 = (30%) There is a maximum of 255 characters. 3000, delay (3000).

drives a pair of DC motors on my tank treads base unit (i. e. , one pair of 12V DC motors). There can be spikes of up to *5 amps when turning (each motor), but the current draw is 2*3 amps going positive and negative. The pros are I'm sorry - Considering that the previous controller was very hot, I am very happy about this because it gets only a little warm. I'm sorry - Wire connectors are included in this board, so this is a major *Less than perfect PWM control of two motors using the control board requires a total of 6 I/O units. There are four I/Os that are used to set FWD/REV, and two additional I/Os The controller does not have an onboard 5V supply, so you would need to add another wire to the board for 5V (although the amount of current required is low since it is just for I had trouble understanding what the "+5v" pins do in the manual that came with the board If you do not connect 5V to the logic, you will not be able to operate the board. Please accept my thanks for this information.

Overall, it seems this is exceeding the 60A limit for my 12V 6A battery A torque motor should be able to handle such a task. The company's instructions can, however, make you waste a great deal of time, as other reviewers have pointed out! One of the following statements is patently false A constant voltage of DC 3 is the control signal voltage Moreover, a positive inversion control signal is present in the enable and the 5V signals". There is a major mistake here and the pin has been marked as "+5V" yet 5V will not work! By switching the +5V (with the help of a 5V power supply) to +3, I activated the safety switch. As soon as I plugged it in at 3V (from the Raspberry Pi), it started working fine. There are numerous places in the instructions that mention "+5V" so I find this a baffling error. The motor controller, otherwise, worked fine. I would have given it a 5 star rating if the directions were accurate.

I am re-starting the system from completely scratch As I write my review, I will consider this. The Raspberry Pi 3 is being used to drive the board. There are a few points you should keep in mind As per the instructions, I applied 5V and a ground from my PI3 to the board's control pins. The power light for the control pins is turned on and all the control pins are set to a voltage just over 5V or a I had a difficult time grasping this concept at first, but once I figured it out, I was able to adjust my programming accordingly. The second one. It is perfectly possible for me to activate Motor 1. am able to activate motor 2 with no problem. There is a problem with activating both at once. If I do that, then the boards seem to get confused on which one they should be Using the 1000ms delay between starting the first and second motor, I was able to replicate this problem. As both started and ran in the allotted period of 5000ms, they need not be in real time. I assumed that the board would require a delay between turning on its individual outputs. In addition, the more resistance on the motors, the longer this delay would need As a result, I need a delay of 500ms if I put the chassis up on a stand. As soon as I put the chassis on the ground with the wheels on the ground, it has to be over 1000ms. Based on my conclusions, it appears there is interference or confusion in the control board when both tasks are being performed simultaneously.

I am going to try powering the controller with an Arduino Uno and see if that helps. is possible that the board isn't designed to work with the Pi 3. My results will be posted here for future buyers so they can get a better understanding of this product as the instructions are not very clear and the company's website is incomprehensible and does not mention this product at all. I have updated It took some time to figure out what was wrong with this board. Next, I wrote code to enable the motors at their maximum As with the PI3, I had the same jumpy results. As soon as I switch from PWM to PWM, everything works fine. It's finally here. It appears that this board is only capable of handling a slow increase in speed when using more than one motor at one time. Either way, this product does not live up to its claims, so I did not award it a whole five.
