Double H driver module uses ST L298N dual full-bridge driver, an integrated monolithic circuit in a 15- lead Multiwatt and PowerSO20 packages. It is a high voltage, high current dual full-bridge driver designed to accept standard TTL logic levels and drive inductive loads such as relays, solenoids, DC and stepping motors. Two enable inputs are provided to enable or disable the device independently of the input signals. The emitters of the lower transistors of each bridge are connected together and the corresponding external terminal can be used for the connection of an external sensing resistor. An additional supply input is provided so that the logic works at a lower voltage.

i need to limit the output current to about 100ma
Sorry , we do not have this example. For this function, you could refer to the datasheet L298 .,
Hi, I want to connect to DC motors with 1.6A stall current each.
Is this driver capable of manage that amount of current or the 2A limit is for the sum of the 2 motors stall current?.
Hello, the total DC current is up to 4 A.
I am using this driver with arduino 2WD platform and arduino mega board, and i have noticed that the plaform is not driving in straight line when both motors are spinning the wheels in same direction. The platform is turning slightly left (or right) wh
Two leaves are not exactly same to each other in the world,the same to the motor.So maybe we use the same style of motor,but we can't get the same speed.For your question,you can speed your right motor or slow your left motor,in a word,you can get the
Can't get it to work with a Netduino.
I'm using a power supply that outputs 24V DC 5.0A connected to VMS and GND ad the power Led lights fine.
Settings from Netduino:
EA to 3.3V
Result is that one of th
Ok, I'll try that. In my setup I gave it 3.3V. I'm a newbie so I'm a little confused when I read the speccifications and they say:"Enable signal level: Low -0.3V~1.5V, high: 2.3V~Vss", so anything above 2.3V would be high, have I misunderstood that?
Well, glad someone has seen the Light, How about Sharing some! Please post your example for the rest of us. I am stuck.
Dear customer,Better you can go to forum there is more people can see you problem and help you.
If you pull a 'SENSE' jumper off, it stops current.
Has anyone got an example circuit/code to make use of those pins ? Or maybe for the 'stepping motor' pins ? There is nothing in the docs...
Hi there, first you can view the datasheet, this Driver shouldn't use code to control.There is told you in datasheet just use LOW/HIGH voltage.
Can anyone please help me connecting this motor shield to an Ardunino mega?
I don't find any tutorial, and the datasheet is to dificult for my basic knowledge... :-( I want to use it to run the amazing 4wd plataform... :-)
Sorry, now I have seen the light, and I have the solution.
