DRV8833 DC/Stepper Motor Driver Breakout Board
PRODUCT ID: 3297
Description
Spin two DC motors or step one bi-polar or uni-polar stepper with up to 1.2A per channel using
the DRV8833. This motor driver chip is a nice alternative to the TB6612 driver. Like that chip, you
get 2 full H-bridges, but this chip is better for low voltage uses (can run from 2.7V up to 10.8V
motor power) and has built in current limiting capability. We set it up for 1A current limiting so
you don't get more than 2A per chip, but you can also disable the current limiting, or change it
to a different limit!
We solder on DRV8833 onto a breakout board for you here, with a polarity protection FET on the
motor voltage input. Each breakout chip contains two full H-bridges (four half H-bridges). That
means you can drive two DC motors bi-directionally, or one stepper motor. Just make sure
they're good for about 1.2 Amp or less of current, since that's the limit of this chip. They do
handle a peak of 2A but that's just for a short amount of time, if you turn off the current limiting
we set. What we like most about this particular driver is that it comes with built in kick-back
diodes internally so you dont have to worry about the inductive kick damaging your project or
driver! You also don't have to worry as much about burning out the chip with overdriving since
there is current limiting.
There's two digital inputs per H-bridge (one for each half of the bridge), you can PWM one of the
inputs to control motor speed. Runs at 2.7V-10.8V logic/motor power. The motor voltage is the
same as the logic voltage, but logic voltage from 2.7V or greater will work so no need to worry if
you are powering the motors from 9V and using 3.3V logic. For higher voltages, check out the
TB6612. For
much
higher
voltages and currents check out the DRV8871!
Comes as one assembled and tested breakout plus a small strip of header. You'll need to do
some light soldering to attach the header onto the breakout PCB. Arduino, motors, and power
supply not included.
