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 2 click,
with its embedded state
machines, is especially suited for designing
motion control user interfaces. It allows
you to implement gesture recognition.
User-defined programs can distinguish
movement patterns like shake and double
shake, face up and face down, turn and
double turn, and activate an interrupt upon
their execution. An integrated FIFO buffer,
with multiple operating modes, enables
you to optimize between performance and
power consumption.
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.
1. Introduction
Accel 2 click
carries
ST’s LIS3DSH IC,
a
low-power factory-calibrated three-axis
accelerometer which embeds a FIFO buffer
and two programmable state machines.
The board communicates with the target
board MCU through either SPI (CS#, SCK,
SDO, SDI) or I2C (SCL, SDA) interfaces. It
also has an interrupt pin (INT) which can
be programmed to respond to user defined
movement patterns.
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.
