Stepper Motor Driver Ic L297 L2983/12/2023 Of course, you can always use relays if you want real old school. If you want more basics on the h-bridge, we’ve covered it many times. ![]() If you know how to use the L298N, you can probably just snag a break out board, download the library, and be off to the races - no pun intended. Of course, the TB6612 drops much less voltage which is great if you are using low voltage motor.Īssuming the new device is suitable for your hardware, the software isn’t really very different from L298N programs. 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.
