    Maybe you could use something like these? There are all sorts of options.

    It would be helpful if you specified package type, what kind of board (custom PCB, strip board, pad per hole), and space available.

    Use solder. That's what everyone else does.

    I never got those things. You still need to solder! :( Maybe to make prototyping easier?

    If you need to control a motor, there are some daugtherboards for motor control. Some of them could have that IC, or some other that controls the motor kind you have: https://www.pololu.com/category/9/motion-control-modules

    Will not have the same freedom than using the IC directly, but it's ready to use, if soldering SMT ICs is an issue.

    Thanks. It uses the smt ic chip from ti drv8881E which is a 28 pin chip. Ideally a breakout board for this chip but who supplies this?

    That part comes in two different SMT packages.

    And both have thermal pads, for which you will need to use hot air to reflow the part properly. Not a good choice for someone who has little experience with smd.

    Post #6 gives you a viable option. Why do you seem to reject that? Another option is to get or build the equipment needed and learn to solder it. Third, find another chip for your project that is not so challenging to solder.

    Let's start with why you picked that chip out of the plethora of motor control chips available? That is, what advantages attracted you to it? What are you using it for?

    If you want to use this chip and do it right, you have to make a proper pcb and learn how to solder it. As jpanhalt suggests, if you are not absolutely stuck with this one, choosing a different chip would be the easiest option.

    Using the smaller of the 2 pkgs. Breakout board as suggested should work. Who supplies it?

    Why couldn't you just say you were using the WQFN package??

    You're going to need something like a reflow oven to solder the thermal pad. Do you have access to appropriate soldering equipment?

    Wayne suggested a breakout board. Looked at the links suggested here but could not find one for Drv 8881E

    You might try contacting a company that makes them https://schmartboard.com/smt-to-dip-adapters/

    They specialize in SMT to DIP adapters and they don't have one...

    Another option is to make your own.

    Or use an available board with a different IC. Why it does to be that one?
