1. Introduction
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
Turn the board upward again. Make sure
to align the headers so that they are
perpendicular to the board, then solder the
pins carefully.
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
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.

clickSTEPPER
Stepper Click™ allows you to drive a bipolar
step motors in full-, half-, quarter- and eighth-
step modes with output drive capability of
30V and about ±500 mA. In order to connect
the motor with the board, solder either a B5B-
XH-A connector or two screw terminals (both
provided with the package). Use jumper J3 to
select whether you want to power the motor
driver with the on-board or external power
supply connected to the CN2 screw terminal.
STEPPER click™ is a stepper motor driver
board in mikroBUS™ form factor. It features
the A3967SLBT microstepping motor
driver with a built-in translator. Stepper click
communicates with the target board via AN,
RST, CS, PWM and INT lines. The board is
designed to use 3.3V or 5V power supplies. A
LED diode serves as a power indicator.

7. SMD Jumpers6. Connectors
If you want to use the motor driver’s enable
pin (#EN), solder J4 SMD jumper in ON
position. Otherwise leave it in the default
OFF position (connected to the ground).
There is a single SMD jumper (zero-ohm
resistor) J1 which is used to select between
3.3V or 5V power supplies. By default, it’s
soldered in the 3.3V position.
Two types of connectors are supplied in the
package: A B5B-XH-A connector, and two
screw terminals. Solder either one or the
other depending on the motor you want to
connect.
