DROK® Mini Stepper Motor L298N DC Stepping Motor Controller Driver Shield Dual-channel H-bridge Micro Arduino Control Driving Board 5V-35V Tiny Motors Driver Module for Smart Car Robot

This product comes with no documentation. I almost gave it 3 stars because of this.The product title claims that this is a stepper motor controller. Apparently it can be used as a stepper motor controller for a single stepper motor. Alternatively you can use it as I am, to control 2 DC Motors (9v).The speed and direction can be easily controlled using arduino. There are 2 output pins for each motor. There are 3 pins for power: a ground, a 5V (for the electronics/logic) and a motor supply voltage (5v to 35v). There are 3 control pins for each motor: pin enA is motor A's PWM pin. It comes supplied with a jumper which needs to be removed if you don't want voltage to be on full. pin in1 and pin2 control the direction of the motor.A. Pulling in1 high and keeping in2 low will send motor forward, pulling in2 high and in1 low will send motor backwards. I'm guessing if both are high or low it may cause motor to break or coast (or short!!) - not tried it.I've successfuly varied speed and direction of a 9v dc motor that I pulled out of a RC car. I presume the other channel will behave similarly.Unlike some other L298n boards - this does not come with any leads. If this product came with a set of 6 female to male 2.54 leads that would have been helpful as I didn't have these and couldn't use the controller until I'd purchased some.Search google for Control-DC-and-stepper-motors-with-L298N-Dual-Moto for a good instructable for a very similar board.

I received this driver in prompt time and for the money you really can't complain, it's of sturdy build and it runs really well with effectively no lag.There are however a few points that should be noted, my personal driver had an overlap of solder that caused a short the first time I used it and from an earlier review I've seen with a connector soldered the wrong way I highly recommend you double check everything before you blow something important like a microcontroller.Next, the usable range, the listing states anything from 5v up to 35v can be used to drive the motor(s) however the driver itself is marked for 12v to drive the them, I thought it best to explore this discrepancy and from my own calculations I wouldn't recommend anything above 15v for 2 DC motors (probably best stick to the 12v) and nothing above 18v for a single stepper, in addition to this its important to note that the supplied heatsink can get hot even without much load.I haven't been able to test this with a stepper motor but from the performance with the motors I'm running I'd imagine it would be fine.All in all, a good board for a small project but if you need quality electronics you're always going to have to pay the price for them.

Arrived quickly. Good protective packaging. A well made product. Connected to nema 17 stepper motor running at 6v (my choice) with excellent reliability and plenty of torque and no over heating. Recommended product if you are looking for a stepper motor driver. Would buy again if needed.

I bought this to control a stepper motor, but that is obvious not the purpose of it. The controlling isn't very good and the stepper skips steps all the time, whilst making weird noises.Ended up changing it.

All seems fine except the connector for out 1 and 2 has been connected back to front, should be fixable.No, 60mins with the soldering iron hasn't fixed the problem, no idea how they decided to attach the fixtures.Total rubbish and now in the bin, don't take the risk

I really like this H Bridge by Drok and its powering my K9 Robot presently.Build quality seems good compared to the previous H Bridge I had that broke.

Really great little gadget and very easy to use with an Arduino. We used this to automate a lego train but you can use it with anything motorised and can even use it to control a step motor (for steering etc.).

Great motor control module - would recommend.

Works reliably.

All is good. Thanks. Product as described

Good driver. Bought it for prototyping with Arduino and it worked well. Remember to connect the 5V supply from the driver to the Arduino V.in.Thank you.

items did not work returned

Perfect little controller and does exactly what it's supposed to.

Works well no problems well worth money Thank you

I have now bought a lot of these and have 7 working robots using them. They drive steppers up to NEMA 17 size without overheating if correctly driven, and also drive converted...

Works perfect for driving my Nema 17 stepper motor connected to an Arduino.

The device works great! I am a happy customer.

works really well
