mikroElektronika Pressure click User manual

1. Introduction
Once you have soldered the headers your
board is ready to be placed into 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 of the pins are
aligned correctly, push the board all
the way into the socket.

4. Essential features
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
bottom side is facing you upwards. Place
shorter parts of the header pins in both
soldering pad locations.
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.

0 100000 023730
Pressure Click™is an accessory board in
mikroBUS™form factor. It’s a compact
and easy solution for adding pressure
measurement to your design. It features
LPS331AP digital output pressure
sensor. Pressure Click™communicates
with the target board microcontroller via
mikroBUS™ SPI (MOSI, MISO, SCK, CS),
I2C (SDA, SCL) and INT lines. The board
is designed to use 3.3V power supply
only. LED diode (GREEN) indicates the
presence of power supply.
Pressure click
Pressure Click™ with it’s LPS331AP IC is
an ultra compact absolute piezoresistive
pressure sensor capable to measure
pressure (260-1260 mbar) or temperature
(-40°C to 80°C) and provide a digital signal
to main board microcontroller. All these
features make this board ideal for indor and
outdor navigations, altimeter or barometer
for portable devices, weather station
equipment, sport watches and many more.

6. SMD Jumpers
The Pressure Click™ board
communicates with the main
board microcontroller via I2C or
SPI interface depending on the
position of the J1, J2, J3 and J4
SMD jumpers. These jumpers are soldered in
I2C interface position by default. There is an
option to select the alternate address with
jumper J5 in the case of I2C interface (default
position is logic 1).
