DROK Micro Electric L298P Motor Driver Module H-bridge Drive Shield Board Microcontroller High-Power DC Motor Controller Bluetooth Interface Build in PWM Speed Controller Compatible with Arduino UNO for Generator Auto Car Vehicle Automotive

This motor shield works very well, but has one issue. That issue is that there is a lack of documentation with it. The board clearly has a lot of features beyond what you would expect from a motor shield. There are headers labeled for connecting to bluetooth modules and an ultrasound sensor, but it's largely trial and error to get it to work without a proper source of information beyond the product description (which has a few typos and is missing a lot of information). If they have some real documentation, this will be a 5 star product.However, the quality of the hardware itself was good. The buzzer works, the motors can be connected through screw terminals or female headers (which is perfect for the Runt Rover I was using it with), and I was able to get it driving around once I figured out the pins that would turn the motors on. If anyone is curious, it can also drive motors using the power from the Arduino's USB port if needed (even if not recommended).I was using this for small robots with lower voltage DC motors, so I didn't run into any issues with heat. The review claiming it draws power when not in use is correct, but that's true of any electronic device, including the Arduino you'll likely be pairing this with.

No instructions included, and I was unable to find any online either. It was a guessing game, Until I blew the voltage regulator on accident.This Module, has hookups for Bluetooth. It does NOT come with Bluetooth. Works very well with an HC-05 or HC-06.it was built very nice though. sturdy construction, Clean solder joints. and easy to use screw terminals.Overall for someone who knows how to use a motor driver I say go for it.Buit for someone just get into the game, This is a great starting point.  Qunqi L298N Motor Drive Controller Board Module Dual H Bridge DC Stepper For Arduino  You can find my review over there also.

So, my Drok L298P board had a solder bridge on the bottom, which I had to remove. Poor QC.Additionally, there was no documentation. I found the datasheet for the L298 IC online. And had to ohm out the pins on the board to figure out what was connected to what. Here's what I found. Hopefully it saves you time:Pin 13 - IN3Pin 12 - IN1Pin 11 - ENBPin 10 - ENAPin 4 - Buzzer (output high to activate)At the top of the board are 4 pinsMotor a+ is OUT4Motor a- is OUT3Motor b+ is OUT2Motor b- is OUT1So, if you want to drive motor b, control direction with IN1, gpio12 and enable it with ENA gpio10If you want to drive motor a, use IN3 gpio13 for direction, and enable it with ENB gpio11

Good product with lots of interface possibilities. Biggest negative is the very limited and error filled documentation. Unless you have a pretty solid idea how this shield should work and what pins on the Arduino are capable of what functionality, you would not be able to use it as intended. Example, the four motor control pins are listed as "(D .D10. D11. D12)" so which one is missing, 9, 13 some other pin (it's 13)?

Works great for my odd little project. Passed through power to the outputs just as expected. Quality seems good enough and there are lots of programming options on this shield.

My grandson and I had this working driving our dual motor, three wheeled robot in under an hour. I now have gotten a second one that I plan to use in a similar experiment.

No documentation in product or available anywhere online. Dont waste your time, buy something else. Also hate the euro screw terminals, the wires never stay in.

Had good experience with this driver module. Used it to control a motors and modified Servos, to control a autonomous obstacle avoidance robot. was great and easy to use.
