1. Introduction
BUZZ Click is an accessory board in
mikroBus™
form factor. Board features
a piezo speaker capable of emitting audio
signals. Buzzer’s resonant frequency is 3.8kHz
(where you can expect it’s best performance).
On-board buzzer driver can be connected
to either digital (GPI) or PWM line. You can
use either of those two pins to provide the
signal from the microcontroller to the buzzer
driver. Board is set to use 5V power supply by
default. Solder

SMD jumper to 3.3V
position if used with 3.3V systems.
Once you have soldered the headers your
board is ready to be placed into 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
board is ready to be placed into 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. Creating Sound
On-board buzzer driver can be connected
to either digital (GPI) or PWM line. You can
create sound using Sound library supported
in mikroElektronika compilers, or utilize
microcontroller internal PWM module to
create the signal for the buzzer. Signal
frequency determines the sound pitch, and
the duty cycle determines the amplitude
(sound volume).

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
bottom side is facing you upwards. Place
shorter parts of the header pins in the
both soldering pad locations.

Before using your click board, make sure
to solder the provided 1x8 male headers
to both sides of the board. Two 1x8 male
headers are included with the board in
the package.
