    Y use a standard servo board to control small motors (or big ones using an H-bridge).

    The servo board has 2 IC, one of them with 7 pins, and it gets too hot when driving current in one of the two ways. And the motor doesn't run smoothly in that direction. It only draws 80-100 mA.

    The IC has a label, BAL8666 and 006 H90: what is it? May I get a replacement?

    Well you can probably get a replacement by going to a radioshack and asking them to crosscheck the numbers to see if it is anything that they can get. <<<BUT>>> I do not envy the task of replacing any IC that has been put on a board IC by a machine... Its a Soldiering Nightmare
