Can I drive a 4WD robot using a single TB6612FNG motor driver. I have been using the L298N motor driver with 4WD robots. To use a single L298N driver to drive 4 wheels I connected pairs of wheels in parallel since the L298N can control only two motors. Can I do the same with the TB6612FNG?

I haven't tried, but I suspect you could, I don;t see a problem with trying.

My personal scorecard is now 1 PC hardware fix (circa 1982), 1 open source fix (at age 82), and 2 zero day bugs in a major OS.

@zander Thank you, but I am afraid. Will this not cook the TB6612FNG if I use a 11.1 V power source to drive the four motors? I am using the common yellow motors.

You don't have to guess any of this. Look up the specs to find out its limits and the requirements for the motors. I see it has a built in thermal shutdown circuit. The max current drawn by a dc motor can be found if you stall the motor (stop the shaft turning) while monitoring the current.

@tmatatu The simple approach is to look at Bill's (DronebotWorkshop) article/video on the subject. Here is the link https://dronebotworkshop.com/dc-motor-drivers/ I am also including the spec snapshot Bill did for each controller. As he says the TB6612FNG is a compatible replacement.
