Pololu's Tic T249 USB multi-interface stepper motor controller, from their own CAD: a 38.10 × 28.57 mm board rated 10–47 V and about 1.8 A per phase continuous (4.5 A only with additional cooling), with 0.1 inch pads down both edges and a 6-way screw terminal block for motor and power.
One of the Tic Stepper Motor Controller family.
