The TB6612FNG Motor Driver can control up to two DC motors at a constant current of 1.2A (3.2A peak). Two input signals (IN1 and IN2) can be used to control the motor in one of four function modes: CW, CCW, short-brake and stop. The two motor outputs (A and B) can be separately controlled, and the speed of each motor is controlled via a PWM input signal with a frequency up to 100kHz. The STBY pin should be pulled high to take the motor out of standby mode. Due to popular demand, this version of the SparkFun Motor Driver includes pre-soldered male headers for ease of use. With the headers already soldered on, you can jump right in to using this little board without any assembly!
Logic supply voltage (VCC) can be in the range of 2.7--5.5VDC, while the motor supply (VM) is limited to a maximum voltage of 15VDC. The output current is rated up to 1.2A per channel (or up to 3.2A for a short, single pulse).
The board comes with all components installed as shown. Decoupling capacitors are included on both supply lines. All pins of the TB6612FNG are broken out to two 0.1" pitch headers; the pins are arranged such that input pins are on one side and output pins are on the other.
Note: If you are looking for the SparkFun Motor Driver without headers, it can be found here or in the Similar Products below.
This skill concerns mechanical and robotics knowledge. You may need to know how mechanical parts interact, how motors work, or how to use motor drivers and controllers.
Skill Level: Rookie - You will be required to know some basics about motors, basic motor drivers and how simple robotic motion can be accomplished.

If a board needs code or communicates somehow, you're going to need to know how to program or interface with it. The programming skill is all about communication and code.
Skill Level: Rookie - You will need a better fundamental understand of what code is, and how it works. You will be using beginner-level software and development tools like Arduino. You will be dealing directly with code, but numerous examples and libraries are available. Sensors or shields will communicate with serial or TTL.

If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.
Skill Level: Rookie - You may be required to know a bit more about the component, such as orientation, or how to hook it up, in addition to power requirements. You will need to understand polarized components.

Worked as expected for powering small dc 6 motor with a fan attached. I'm new to this, but I was surprised how wide the speed range.

Basically it is a very good driver and is easy to use as is.
Improvements to consider: Currently there is no way to mount the board short of double back tape. Four (4) small holes would be nice say big enough for # 2-56 screws
Added feature (option) 1.5 amps is nice for small motors. You might think about developing an add-on board or maybe another board to allow for the use of larger motors, say 5 amps or more.
The board I have I will use as is for the time being but I when I move on to a larger project, I will add a set of four (4) MOS FETs to allow me to drive much larger motors.
All in All, I like the board and will use it in my current project and will probably get another one along with some MOS FETS to increase the boards capacity.
While I know that my application was pretty close to the current limit for this product, the SparkFun Motor Driver has performed flawlessly. It was easy to interface with an Arduino Pro Mini and the coding was trivial. I am using these for prototypes of an electro-mechanical product that I am currently developing and will likely purchase several more as I continue to fabricate more prototypes. I will obviously transition away from this module for production...will probably still use the TB6612FNG IC.
The TB6612FNG worked perfectly !
I was looking for some 3.3.V brush motor drivers. These worked great. What made them especially easy to use was the excellent driver library !!!. Thank you so very much for both the motor driver and library. Merry whatever you celebrate and have a very Happy New Year !!!
PS Mr robot also thanks you.
I'm driving a couple of 37 mm diameter 12 V brushed DC motors with attached gearboxes on the bench with an Arduino clone. So far, so good.
I'd like to see a larger version of this board with some moderate-brightness indicator LEDs (especially on VM, VCC, and PWMA and PWMB) to make debugging and status checking easier. Of course this would make them more costly, but sometimes cost and size aren't as important as the ease of getting up and running.
I build robots. I have been using l298n motor drivers. But I just tried a TB6612FNG and it works just fine with 4 6 volt motors and a 12 volt 8xAA power source. My only problem was fitting all the dupont jumper connections onto the circuit prototype board. I will use the TB6612FNG from now on.
