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.

The
MPU–9150
aboard MPU 9DOF click
™
is
designed for the low power, low cost and
high performance requirements of consumer
electronics equipment and wearable
sensors. The ability to track motion in
free space also makes MPU 9DOF click
™
a
suitable sensor when designing remote
controlled quadcopters. The Tri-Axis gyro
has a sensitivity up to 131 LSBs/dps and a
full-scale range of ±250, ±500, ±1000, and
±2000dps; the Tri-Axis accelerometer with
a programmable full scale range of ±2g, ±4g,
±8g and ±16g; and the tri-axis compass has
a full scale range of ±1200µT.
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.
MPU 9DOF click
™
carries the
MPU–9150
SiP (System in Package),
which is the
world’s first 9-axis MotionTracking device.
The device comprises two chips: one is
the
MPU–6050
that contains a 3-axis
accelerometer, a 3-axis gyroscope, and a
DMP (digital motion processor); the other
is
AK8975,
a 3-axis digital compass.
MPU 9DOF click
™
communicates with
the target board through
mikroBUS
I2C
(SCL, SDA), INT and RST (FSYNC) lines. It’s
designed to use a 3.3V power supply only.
™
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.
