Ultra-efficient MOSFET-based dual motor driver. Controls two DC motors with PWM speed input, operating on 2.7V-5.5V logic and 4.5V-10V motor power.
Next-generation efficiency for compact robotics. The TB6612FNG Dual Motor Driver is the modern standard for driving small DC motors. Unlike older bipolar drivers (like the L298N or L293D) which suffer from massive voltage drops and require huge heatsinks, the TB6612FNG uses MOSFET components. This means your motors get almost the exact voltage you supply from your battery, resulting in longer runtimes and zero need for active cooling.
Advanced Control Logic The breakout board carefully splits the power and logic domains to protect your microcontroller. The VCC pin handles the logic supply (2.7V to 5.5V), while the VM pin provides the raw power to the motors (4.5V to 10V). To drive Motor A, you supply direction logic to AIN1 and AIN2, and a PWM signal to PWMA to control the exact speed. A crucial feature of this board is the STBY (Standby) pin; it must be pulled HIGH for the motors to operate, providing a convenient way to instantly disable all movement to save power or act as an emergency stop.
Driver IC: TB6612FNG
Logic Supply Voltage (VCC): 2.7V to 5.5V DC
Motor Supply Voltage (VM): 4.5V to 10V DC
Output Current: 1.2A continuous per channel (3.2A peak)
Motor Channels: 2 Independent DC Motors (A01/A02 and B01/B02)
Speed Control: Independent PWM inputs (PWMA / PWMB)
Standby Mode: Hardware STBY pin for power saving
Micro-Robotics (Micromouse/Line Followers): Driving tiny N20 micro gear motors with extreme precision where space and battery weight are limited.
Mecanum Wheel Cars: Using two of these modules to drive four independent wheels for omnidirectional robotic movement.
Camera Gimbals: Smoothly controlling small pan/tilt mechanisms utilizing the high-frequency PWM capabilities.
Unlock New Capabilities (Project Evolution)
Battery Upgrade: Because there is minimal voltage drop, you can transition from heavy 12V lead-acid batteries to a compact 2S LiPo battery (7.4V) connected to the VM pin and still get maximum torque from your 6V motors.
Safety Upgrade: Connect the STBY pin to a dedicated emergency-stop button or a bumper switch on your robot; when pressed, it pulls STBY LOW and immediately halts the drive without complex code.
Package Includes:
1 x TB6612FNG Dual Channel Motor Driver Module
2 x 8-Pin Male Headers (Note: These are included loose and require soldering)
What is the difference between VM and VCC? VM is the raw power supply for your motors (4.5V-10V). VCC is the low-voltage power for the logic chip (2.7V-5.5V).
Why aren't my motors turning? You must pull the STBY (Standby) pin HIGH. If STBY is disconnected or LOW, the module is in sleep mode and will not drive the motors.
Are the header pins pre-soldered? No, the module comes with two loose 8-pin headers that you must solder yourself before it can be used on a breadboard.
How do I control the motor speed? Send a Pulse Width Modulation (PWM) signal from your microcontroller to the PWMA (for Motor A) or PWMB (for Motor B) pins.
How do I change the motor direction? For Motor A, toggle the AIN1 and AIN2 pins. If AIN1 is HIGH and AIN2 is LOW, it spins one way; flip them to reverse the direction.
Can I power the motors from my Arduino's 5V pin? You can power the logic VCC from the Arduino's 5V pin, but you should never power the motor VM from the Arduino. Always use a separate battery or power supply for VM.
Is there a common ground requirement? Yes, the GND pins are shared internally. You must connect your motor battery's ground and your Arduino's ground to the module.
Where do I connect the DC motors? Motor A connects to the A01 and A02 pins. Motor B connects to the B01 and B02 pins.
What is the maximum current rating? The chip is rated for 1.2A of continuous current per channel, with brief peak bursts up to 3.2A.
Why use the TB6612FNG instead of the L298N? The TB6612FNG uses highly efficient MOSFETs, so it doesn't waste battery power as heat, it doesn't need a massive heatsink, and it is significantly smaller.
Can it drive a stepper motor? Yes, you can drive a single 4-wire bipolar stepper motor by treating the two coils as two separate DC motors.
What exactly does the STBY pin do? The STBY pin controls the working status. When pulled LOW, the module enters a low-power standby state, disabling all motor outputs to save battery.
What happens if I make AIN1 and AIN2 both HIGH? This triggers a "Short Brake" mode, actively resisting the motor's rotation to stop it quickly.
Is it compatible with 3.3V boards like the ESP32 or Raspberry Pi? Yes, the VCC logic accepts 2.7V to 5.5V, making it perfectly safe and compatible with 3.3V controllers.
Can I parallel the outputs to drive one larger motor? Yes, you can bridge A01 with B01, and A02 with B02 to essentially double the current capacity for a single motor (up to 2.4A continuous).
Does the module have thermal protection? Yes, the TB6612FNG IC includes a built-in thermal shutdown circuit that disables the outputs if the chip gets too hot.
Do I need external flyback diodes? No, the internal MOSFETs have built-in body diodes that safely handle the inductive voltage spikes generated by the motors.
What is the maximum PWM frequency it supports? The module supports high-frequency PWM input up to 100 kHz, allowing for extremely smooth and silent motor operation.
Can I use this to drive a solenoid or relay? Yes, because it is an H-bridge, it can drive other inductive loads like solenoids or electromagnets up to 1.2A.
What happens if the motor voltage (VM) drops too low? The chip features a low-voltage detecting circuit. If VM drops below the operational threshold, it will protect the circuit by disabling the motor outputs to prevent erratic behavior.

We are into electronics & mechanical projects in this connection we had contacted probots & we visited them , To our pleasant surprise , their presentation with us was friendly wrapped with professional support , which helped us to choose better , this interaction was patient & excellent .with all confidence i shall promote them to my known sources looking for components . Pls maintain this attitude towards customer this shall take your organization to heights
Great place to get all electronic components and accessories for electronic products.
I had ordered something, will write review after the order process is complete.
Ordered a couple of times, Bad Experience. They charge premium delivery fee but delivery will not happen on time(every time). And the resopnce after sales on the issues such as delivery is slow and not friendly. If you can take the delivery at your own risk, and liesure you can order.
I would like to share a suggestion based on my recent experience. I am also running a private limited company and understand how important customer relationships are. One key area that needs attention is training employees on how to deal with customers professionally and respectfully. No business starts with bulk orders—every relationship begins small and grows with trust. I had some plans to collaborate when I visited your facility, but unfortunately, due to the way I was treated, I decided not to proceed with any future business plans. I believe this is not a reflection of the owner, but rather an issue with employee conduct. Proper training and customer handling can significantly improve business growth and reputation. As I do not have a direct contact, I am sharing this feedback here. If you would like to discuss further, please feel free to contact me. Our recent bill was under the name Electro Instruments.
Fast Delivery, Accurate information, Quick resolution, most important acceptance & accountability and willingness to help.
