Dual TB9051FTG Motor Driver Shield for Arduino.
The Pololu dual TB9051FTG 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. The board features a pair of Toshiba TB9051FTG motor drivers, which operate from 4.5 to 28 V and can deliver up to 2.6 A per channel continuously, and includes current sense circuitry, reverse battery protection, and logic gates to reduce the required number of I/O pins. The drivers automatically limit the peak current to around 5 A, which they can deliver for a few seconds in typical applications before the thermal protection activates. It ships fully populated with its SMD components, including the two TB9051 ICs, as shown in the picture to the right; stackable Arduino headers and terminal blocks for connecting motors and motor power are included but are not soldered in.
This versatile motor driver 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 general-purpose dual-channel version of our single-channel TB9051FTG carrier to use with other microcontroller boards, outside of the Arduino environment. The Arduino pin mappings can all be customized if the defaults are not convenient, and the simplified TB9051FTG control lines are broken out along the left side of the board, providing a convenient interface point for other microcontroller boards.
