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.

4. Essential features
Accel Click™ with it’s
ADXL345
module
supports several sensing functions such as
single/double tap detection, activity/inactivity
monitoring, free-fall detection etc. It has
memory management system with a 32-level
FIFO buffer to store data with minimized host
processor activity. All these features make
this board ideal for mobile devices, medical
and industrial instrumentation, navigation
devices, hard drive protection and more.

Turn the board upside down so that
bottom side is facing you upwards. Place
shorter parts of the header pins in both
soldering pad locations.
Turn the board upward again. Make sure
to align the headers so that they are
perpendicular to the board, then solder the
pins carefully.
Accel Click™ is an accessory board in
mikroBUS™
form factor. It’s a compact
and easy solution for adding accelerometer
functionality to your device. It features
ADXL345
3-axis accelerometer module with
ultra-low power and high resolution (13-bit)
measurement. Accel Click™ communicates
with target board via I
2
C or SPI interface. The
Board is designed to use 3.3V power supply
only. It has a LED diode (GREEN) which
indicates the presence of power supply.
3. Plugging the board in
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 of the pins
are aligned correctly, push the
board all the way into the socket.

6. SMD Jumpers
The Accel Click™ board communicates
with the main board via I
2
C or SPI interface
depending on the position of the
J1, J2
and
J3
SMD jumpers. These jumpers are soldered in
I
2
C interface position by default. There is an
option to select the alternate address with
jumper
J4
in the case of I
2
C interface (default
position is logic 1).
