The TB6612 boasts up to 95% efficiency and also has a low current standby mode.
However, because of its relatively low efficiency, it needs a heat sink. For example, the L298N can operate motors from 4.5 to 46V while the TB6612 can go from 2.5 to 13.5V on the motor voltage. looks at several ready-to-go breakout boards. You can get breakout boards for the tiny chips. The TB6612 may be a little more expensive, but it’s clearly worth it. In the video below, he uses a TB6612FNG instead, taking advantage of the device’s use of MOSFETs.
has used L298N chips like this many times. If you want to build a small robot with a motor, you are likely to reach for an L298N to interface your microcontroller to the motor, probably in an H-bridge configuration.
