• Max speed of I2C interface: 3.4 MHz
  
• Current: 2.7 μA at a sampling frequency of 1 Hz
  
• Interface: I2C, SPI (4 Wire), SPI (3 Wire)
  
• Calibration: factory
  
• Noise level: up to 0.2 Pa (1.7 cm) and 0.01 temperature
  
• Pressure measurement range: from 300hPa to 1100 hPa (9000 m to -500 m)
  
• Size: 21 mm x 18 mm
