K5102 Kitronik Digital Barometer Breakout Board (MPL115A2)

This board uses a MPL115A2 digital barometer which can provide a temperature compensated pressure reading. The sensor can measure pressures between 50 kPa to 115 kPa Absolute Pressure with an accuracy of ±1 kPa. The board supports a wide range of input voltages (2.4V – 5.5V) and uses I2C. When selecting an input voltage to use, keep in mind that pulling the SHDN and RST pins above the input voltage will cause malfunctions. On board I2C bus pull-ups are included and can be enabled by attaching a jumper across PL2.

Features:

• Absolute Pressure measurement from 50 kPa to 115 kPa.
• Wide supply voltage range.
