The barometer designed by freescale is used widely due to
its very small miniature size and 8 pin LGA MEMs technology package with metal casing comes in about size of
3mmx5mm (roughly).
The barometer is available in IIC and SPI protocol and very
cheap < 5 dollar in digikey or any other.
This is my first design using the SPI sensor.
The device is now working in 3.3 volt power supply . MIC5225
is SOT23 package 150mA current adjustable LDO regulator.
The final PCB for testing in somewhat like this …
The 3d view is some what like .
The 3d image for the sensor is available in my 3Dcontent central. ..( ).
