SparkFun Altitude/Pressure Sensor Breakout - MPL3115A2

The SparkFun Altitude/Pressure Sensor Breakout - MPL3115A2 is a high-precision MEMS pressure sensor that can provide altitude data accurate to within 30cm when oversampling is enabled. The sensor's outputs are digitized by a high-resolution 24-bit ADC and transmitted over I2C, making it simple to interface with most controllers. The device can output pressure in fractions of a Pascal and altitude in fractions of a meter. It also provides 12-bit temperature measurements in degrees Celsius.

This breakout board simplifies prototyping with this compact device by breaking out the necessary pins to a standard 2.54mm spaced header. The board includes all the passive components required for the device to function, so it can be easily connected to an I2C-compatible device to start operation.

Features:

• Supply Voltage: 1.95V to 3.6V, internally regulated by LDO
• Digital Interface Supply Voltage: 1.6V to 3.6V
