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
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.
1. Introduction
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 I
2
C
lines (SCL, SDA). The board is designed to
use a 3.3V power supply only.
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.
