The A-Star 32U4 Robot Controller LV with Raspberry Pi Bridge is a programmable module well-suited for robotics applications

without shaft (NEMA 14)

but it can be found in ST application note AN4545 (706k pdf) and design tip DT0037 (386k pdf)

For a higher-power alternative to this shield

and other control inputs and outputs of the MC33926 ICs are accessible on the board for more advanced applications

Pololu A4990 Dual Motor Driver Shield for Arduino hub-sensoren The A-Star 32U4 Robot ControllerThis small shield is an easy, economical way to control two small brushed DC motors with an Arduino or Arduino compatible board. Its integrated A4990 dual motor driver operates from 6 V to 32 V and can deliver a continuous 0. 65 A to each motor channel, making it a great control option for low current motors that run on high voltages. The A4990 is configured to limit the peak motor current to about 0. 9 A per channel and is protected against reverse
