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. 1 Pressure click 2 3 4. Essential features 1. Introduction Pressure Click with its LPS331AP IC is an ultra compact absolute piezoresistive pressure sensor capable to measure pressure (260-1260 mbar) or temperature (-40C to 80C) and provide a digital signal to main board microcontroller. All these Turn the board upside down so that Turn the board upward again. Make sure features make this board ideal for indor and bottom side is facing you upwards. Place to align the headers so that they are outdor navigations, altimeter or barometer shorter parts of the header pins in both perpendicular to the board, then solder the for portable devices, weather station soldering pad locations. pins carefully. equipment, sport watches and many more. Pressure Click is an accessory board in mikroBUS form factor. Its a compact 3. Plugging the board in and easy solution for adding pressure click measurement to your design. It features Once you have soldered the headers your LPS331AP digital output pressure board is ready to be placed into desired BOARD sensor. Pressure Click communicates mikroBUS socket. Make sure to align the www.mikroe.com with the target board microcontroller via cut in the lower-right part of the board mikroBUS SPI (MOSI, MISO, SCK, CS), with the markings on the silkscreen at the Pressure click Manual 2 I C (SDA, SCL) and INT lines.

Pressure Click Board Schematic The Pressure Click board communicates with the main 2 board microcontroller via I C or SPI interface depending on the position of the J1, J2, J3 and J4 VCC-3.3V SMD jumpers. These jumpers are soldered in 2 VCC-3.3V VCC-3.3V VCC-3.3V VCC-3.3V I C interface position by default. There is an R1 2K2 option to select the alternate address with I2C/SPI 2 jumper J5 in the case of I C interface (default LD1 J2 C1 C2 C3 position is logic 1).
