Pololu Dual MC33926 Motor Driver Shield for Arduino - PL-2503 info

Pololu Dual MC33926 Motor Driver Shield for Arduino and its corresponding Arduino library make it easy to control two bidirectional, brushed DC motors with an Arduino or compatible board, such as the A-Star 32U4 Prime. Pololu Dual MC33926 Motor Driver Shield for Arduino features a pair of Freescale MC33926 motor drivers, which operate from 5 to 28 V and can deliver a continuous 3 A per channel, and includes current sense circuitry, protection resistors, a FET for reverse battery protection, and logic gates to reduce the required number of I/O pins. It ships fully populated with its SMD components, including the two MC33926 ICs, stackable Arduino headers and terminal blocks for connecting motors and motor power are included but are not soldered in.

Pololu Dual MC33926 Motor Driver Shield for Arduino is intended for a wide range of users, from beginners who just want a plug-and-play motor control solution for their Arduinos (and are okay with a little soldering) to more advanced users who want a dual MC33926 carrier that requires fewer I/O pins to control. The Arduino pin mappings can all be customized if the defaults are not convenient, and the simplified MC33926 control lines are broken out along the left side of the board, providing a convenient interface point for other microcontroller boards. This versatility, along with an option to power the Arduino directly from the shield, sets this board apart from similar competing motor shields.
