mikroElektronika Altitude 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 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.

Altitude click
Altitude click™is an accessory board in
mikroBUS™form factor. It’s a compact
and easy solution for adding altimeter
to your design. It features MPL3115A2
precision pressure/temperature sensor
which also provides altitude data. Altitude
click™communicates with the target
board microcontroller via mikroBUS™ I2C
(SCL, SDA), INT and CS lines. The board is
designed to use 3.3V power supply only.
LED diode (GREEN) indicates the presence
of power supply.
Altitude click™with it’s MPL3115A2 IC
employs a MEMS pressure sensor to provide
accurate pressure/altitude (20-bit) and
temperature (12-bit) data. Resolution is
down to 30 cm (1.5 Pa). The MPL3115A2
is capable of processing internal data
automatically with data acquisition and
compensation. This makes altitude sensor
an ideal choice for smart phones/tablets,
personal electronics altimetry, GPS systems,
weather station equipment and many more.

Once you have done all the necessary
preparations, it’s time to get your click™
board up and running. We have provided
the examples for mikroC™, mikroBasic™and
mikroPascal™compilers on our Libstock
website. Just download them and you are
ready to start.

5. Altitude click™Board Schematic 6. FIFO buer
The MPL3115A2 features 32 sample
FIFO buer to minimize the overhead of
collecting multiple data samples. The FIFO
stores both temperature and pressure/
altitude data. The IC can be programmed to
collect independently data at programmed
intervals and store the data in the FIFO. It has
ability to log data up to 12 days depending
on data acquisition rate (1 second – 9 hour).
