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 Altitude click 2 3 4. Essential features Altitude click with its MPL3115A2 IC 1. Introduction 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 Turn the board upside down so that Turn the board upward again. Make sure compensation. This makes altitude sensor bottom side is facing you upwards. to align the headers so that they are an ideal choice for smart phones/tablets, Place shorter pins of the header into the perpendicular to the board, then solder the personal electronics altimetry, GPS systems, appropriate soldering pads. pins carefully. weather station equipment and many more. Altitude click is an accessory board in mikroBUS form factor. Its a compact 3. Plugging the board in and easy solution for adding altimeter click to your design. It features MPL3115A2 Once you have soldered the headers your precision pressure/temperature sensor board is ready to be placed into desired BOARD which also provides altitude data. Altitude mikroBUS socket. Make sure to align the www.mikroe.com click communicates with the target cut in the lower-right part of the board 2 board microcontroller via mikroBUS I C with the markings on the silkscreen at Altitude click Manual (SCL, SDA), INT and CS lines. The board is the mikroBUS socket. If all of the pins are ver. 1.00 designed to use 3.3V power supply only. aligned correctly, push the board all LED diode (GREEN) indicates the presence the way into the socket. of power supply. 0 100000 024751 6. FIFO buffer 5. Altitude click Board Schematic The MPL3115A2 features 32 sample FIFO buffer 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). 7.
