Pololu dual MC33926 motor driver shield
for Arduino.
1. Overview
The
and its corresponding
Arduino library make it easy to control two bidirectional,
brushed
DC
motors
with
an
or Arduino clone. The
board 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, 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
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.
