DC MOTOR
1. Introduction
DC MOTOR click is a DC motor driver board
™
mikroBUS
in ™ form factor. It features the
DRV8833RTY
H-Bridge motor driver,
74HC4053 multiplexer and two screw
terminals. DC MOTOR click communicates
™
with the target board via SELECT1,
SELECT2 and nSLEEP control lines, PWM
input line and nFAULT feedback line. The
board is designed to use 3.3V or 5V power
supplies. It has a GREEN power supply
indicator LED and a RED LED that indicates
active nFAULT line (in case of short-circuit).
2. Soldering the headers
Before using your click board, make sure
™
to solder 1x8 male headers to both left
and right side of the board. Two 1x8 male
headers are included with the board in
the package.

Turn the board upside down so that
the bottom side is facing you upwards.
Place shorter pins of the header into the
appropriate soldering pads.

Turn the board upward again. Make sure
to align the headers so that they are
perpendicular to the board, then solder the
pins carefully.
3. Plugging the board in
Once you have soldered the headers your
board is ready to be placed into the desired
mikroBUS ™ socket. Make sure to align the
cut in the lower-right part of the board
with the markings on the silkscreen at the
mikroBUS socket. If all the pins are aligned
™
correctly, push the board all the way
into the socket.
4. Essential features
DRV8833RTY
DC MOTOR click ™ with its
IC's is limited to a 0.9A driving current
with 0.22Ω current sense resistor. The
74HC4053 IC is incorporated into the
design in order to run the motor with only
one PWM line available on the mikroBUS
socket. Use jumper J2 to select whether you
want to power the board with the on-board
or external power supply connected to the
CN2 screw terminal. The motor should be
CN1
connected to the screw terminal.
