2. Soldering the headers
1. Introduction
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.
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
the bottom side is facing you upwards.
Place shorter pins of the header into the
appropriate soldering pads.
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
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.

MPU 9DOF click™
MPU 9DOF click™carries the MPU–9150
SiP (System in Package), which is the
world’s rst 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.

MikroElektronika oers free tech support
(www.mikroe.com/support) until the end
of the product’s lifetime, so if something
goes wrong, we’re ready and willing to help!
Once you have done all the necessary
preparations, it’s time to get your click™board
up and running. We have provided examples
for mikroC™, mikroBasic™and mikroPascal™
compilers on our Libstock website. Just
download them and you are ready to start.

6. Zero-Ohm jumpers
MPU 9DOF click™has two jumpers (zero-Ohm
resistors). FSYNC enables or disables the
interrupt function on the FSYNC (RST)
mikroBUS™pin. I2C ADD allows you to select
between the available I2C addresses.
