mikroElektronika Click Boad Accel Click User manual

1. Introduction
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.

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

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.

Accel click Manual
ver. 1.00
0 100000 020968
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 buer 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.
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 I2C 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.

6. SMD Jumpers
The Accel Click™ board communicates
with the main board via I2C or SPI interface
depending on the position of the J1, J2 and J3
SMD jumpers. These jumpers are soldered in
I2C interface position by default. There is an
option to select the alternate address with
jumper J4 in the case of I2C interface (default
position is logic 1).
