2. Soldering the headers
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 MS5803-14BA is both precise and ro-
bust. The measurement resolution is up to
0.2 mbars, but an antimagnetic stainless
steel cap enclosure allows it to withstand up
to 30 bars of pressure (more than twice the
maximum measurement range). Therefore,
Pressure 2 click™is ideal for developing mo-
bile pressure measurement systems, such
as for adventure watches, diving computers
and similar devices.

Pressure 2 click™carries MS5803-14BA, a
high resolution MEMS pressure sensor with
an operating range from 0 to 14 bars. The
module comprises a high linear pressure
sensor and an ultra low power 24 bit ADC.
It is optimized for depth measurement sys-
tems with a water depth resolution of 1cm
and below. Pressure 2 click™communicates
with the target board MCU either through
mikroBUS™SPI (CS, SCK, SDO, SDI) or I2C
lines (SCL, SDA). The board is designed to
use a 3.3V power supply only.

Pressure 2 click™
carries two sets
of jumpers (zero
ohm resistors).
The group of four
COMM. SEL jumpers is for choosing between
SPI or I2C interface. I2C ADD is for specifying
the I2C address.
