Pololu 2520 Dual TB9051FTG Motor Driver Shield for Arduino
This motor driver shield and its corresponding Arduino library make it easy to control two bidirectional, brushed DC motors with an Arduino or compatible board. 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.
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. 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. This versatility, along with an option to power the Arduino from the shield, either directly or through an added regulator, sets this board apart from similar competing motor shields.
The board ships fully populated with its SMD components, including the two TB9051 ICs, as shown in the left picture above; stackable Arduino headers and terminal blocks for connecting motors and motor power are included but are not soldered in.
This motor driver board ships with all of the surface-mount parts populated. However, soldering is required for assembly of the included through-hole parts. The following through-hole parts are included:

The terminal blocks can be soldered into the larger holes to allow for convenient temporary connections of unterminated power and motor wires or you can break off a 12×1 section of the 0.1″ header strip and solder it into the smaller through-holes that border these larger holes. You can also solder wires directly to the board:
When not using this board as an Arduino shield, you can solder the pieces of the 0.1″ header to the logic connections along the left side of the board to enable use with custom cables or solderless breadboards, or you can solder wires directly to the board for more compact installations. Note that motor and motor power connections should not be made through a breadboard.
