mikroElektronika Shake2Wake click Quick Start Manual

Shake2Wake click
1. Introduction
Shake2Wake click carries an ADXL362
ultralow power, 3-axis MEMS accelerometer
from Analog Devices. The distinguishing
feature of this IC is that it incorporates
several activity detection modes. The
interrupt pins from the chip are connected
to an onboard ADP195 power switch IC
that in turn controls an external device
connected through a screw terminal.
Otherwise, Shake2Wake click communicates
with the target MCU through mikroBUS™ SPI
interface. Uses 3.3V power supply only.
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.

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.
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.
4. Essential features
Shake2Wake click has two main operating
modes: "measuring" and "wake-up" To use
it as a regular accelerometer, for continuous
sensing, use the Measurement mode.
Shake2Wake click outputs 12-bit resolution
data (8-bit also available). The "wake-up"
mode is for activity detection, ideal for motion
activated on/off switches. The detection
threshold is configurable (both intensity and
duration). The duration of inactivity that leads
to switching off is also programmable. In
wake-up mode, the power consumption drops
dramatically (270nA at 2V).
