SparkFun altimeter/barometer (MPL3115A2)

The digital barometer module allows you to measure the height in meters and a pressure in the range of 50 to 110 kPa . The system has an internal 24-bit converter that converts the analog signal to digital. The data is transferred to the microcontroller over the I2C (TWI) interface at a speed of up to 400 MHz. The device also has a 12-bit thermometer that allows temperature measurement from -40 to 85 ° C. 

The sensor operates in the voltage range from 1.95 to 3.6 V. This makes it possible to directly control microprocessors working on this voltage , STM32Discovery, Arduino Pro Mini 3,3 V, or Raspberry Pi Mini. In order to connect the systems to a 5 V voltage, Arduino Uno must be connected via a voltage converter. 

The module can be connected by soldering goldpin connections (purchased separately) with a pitch of 2.54 mm. Conductive strips allow the module to be connected using wires or direct contact.
