What is your go to DC motor driver for Arduino projects

If you want a module ready to use any Pololu board would do the job, just find the one that meets your requirements www.pololu.com/.../brushed-dc-motor-drivers

I usually use Pololu modules, they are very well documented and have enough variety for almost all kinds of applications.

Pololu - Brushed DC Motor Drivers

I see two of these three driver chips on the site

TB67H450FNG
TB6612FNG
DRV8833

What do you do for a library in Arduino? I realize J, you have the skills to bash out code to make it work. I need to be carried on the shoulders of people like you with libraries to get it to work:)

Adafruit has several motor driver cards that are supported with software.

I think that DFRobot has some interesting collection as well

Thanks for the input. I've selected two modules. One is using a TB67H450FNG chip and another mdoule using TB6612FNG. I found some third party Arduino libraries I will use for some testing. 

Nice, I might order one of these as well, and if you get stuck on the Arduino code, I can give it a go too. I don't have any motor drivers for 12V, but do have some stepper motors that might operate at 12V, so that will come in handy anyway.

I can suggest popular DC motor drivers often used in Arduino projects:

1. L298N: This is a widely used dual H-bridge motor driver that can control two DC motors. It's affordable and works well for small to medium-sized projects.

2. L293D: Another dual H-bridge motor driver that's compatible with Arduino. It's suitable for controlling two motors bidirectionally.

3. Adafruit Motor Shield: This is a shield designed for Arduino boards that can control up to 4 DC motors or 2 stepper motors. It offers more advanced features and is great for larger projects.

4. TB6612FNG: This is a compact and efficient motor driver that can control one DC motor or a stepper motor. It's a good choice for smaller projects with space constraints.

5. DRV8833: A small and low-cost motor driver that can control one DC motor. It's suitable for basic motor control needs.

Your choice of motor driver depends on your project's specific requirements, such as the number of motors you need to control, the power requirements, and any additional features you may need. Be sure to check compatibility with your Arduino board and the motor specifications before selecting a motor driver.

LOL ChatGPT suggests the same as you:

I don't know if I ever posted a photo of it, but that H450 driver (which was described here:   Using H450 (Toshiba TB67H450) Motor Driver Boards with Arduino   ) PCB arrived a while back. 

It appears to work fine, can be screwed on top of an Arduino if mounting pillars are available and uses jumper wires to connect to the Arduino. The Arduino library for it that was described at that blog post works fine too. I think it will be more reliable that the L293/298 boards.

In the photo below it was being used not as a motor driver, but for testing inductors, that big resistor was to limit current. Handy to have a H-bridge for various testing purposes.
